First, one must acknowledge that if one adds a group of numbers, the resulting sum will have the same remainder when divided by three as the sum of each number's modulus by three would be. The first four numbers in the Fibonacci sequence, mod 3, are 0, 1, 1, 2. By the rule established in the beginning of this answer and by the rules of the Fibonacci sequence, the modulus of a given number in the sequence is equal to the sum of the previous two, mod 3. As a result, the next four numbers are 0, 2, 2, 1. The rule holds true thus far, with the first number in each set of modulus figures being 0. After that, the next four numbers are 0, 1, 1, 2. As a result, it can be seen that the Fibonacci sequence, modulus 3, has the following patter, which shows that each fourth number is divisible by three: 0, 1, 1, 2, 0, 2, 2, 1.

What is the largest number which divides into every third term of the Fibonacci Sequence?

Which number is a factor of every fourth Fibonacci number?

The fourth Fibonacci number is 3, so the only possible answer is "3". It does indeed look as if every fourth number after that is a multiple of 3.


What is the largest mumber which divides into every third term of the Fibonacci Sequence?

First 18 terms of the sequence are: 1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597, 2584. Every third term is 2,8,34,144,610,2584. These are all even so the largest number is likely 2.


Which number is a factor for every fourth number in the first 15 numbers in the Fibonacci sequence?

If you start with 1, the common factors are 1 and 3. If you start with zero, as Fibonacci did, the common factor is 1.


How does Fibonacci's growing sequence occur in a number of living things?

Yes, like every rap song out there :P


What was Fibonacci's famous mathematical invention?

Fibonacci is most famous for his description of the number sequence, which in the 19th century was given the name 'Fibonacci numbers' . The sequence is made by starting with two ones, and adding them up, then to make every new term, the previous two terms need to be added together.


Can every natural number be expressed as a sum of Fibonacci numbers where no number is used more than once?

Yes.Since 1 is a member of the Fibonacci sequence, it is always possible. Any natural number, N, can be represented as a sum of a string of N ones.Yes.Since 1 is a member of the Fibonacci sequence, it is always possible.

Which Fibonacci numbers are divisible by three?

Every fourth one.


Which number is the odd one out in this sequence 1 1 2 3 5 8 13 21 29?

"29" is the odd one out. because all the other nos. are in the Fibonacci series, and 29 is not. In the Fibonacci series, every number (except for the first two) is the sum of the previous two numbers.


What is a number that divides a given number leaving a zero remainder?

A remainder of zero is obtained whenever the number is divided by its factor. For example, when 20 is divided by either 1,2,4,5,10 or 20 the remainder is zero. Every number has 1 as its divisor.Infact, this is the definition of divisor- a number which divides another number to return zero as the remainder.


What is the ratio of odd Fibonacci numbers to even Fibonacci numbers?

The ratio is 1:2. For every even number there are 2 odd numbers. Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... which is even, odd, odd, even, odd, odd, even, odd, odd, even, ... the pattern continues


What was Fibonacci famous for?

Fibonacci was most famous for his contribution to mathematics, specifically the Fibonacci sequence. The Fibonacci Sequence is as follows: Start with the numbers 0 and 1, add them together you get 1, then add 1 and 1 together you get 2, then add 2 and 1 together you get 3 then add 3 and 2, 5, then 5 and 3, 8, then 8 and 5, 13 and soon below is all the Fibonacci numbers upto 233, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233... In other words each number is a result of the two previous numbers added together. The significance of this is that the higher you get in the sequence, you can divide a number and its previous number and that will give you a number close to the golden ratio (a special number that is used very frequently in mathematics, usually designated by the letter "e"). Fibonacci, or Leonard of Piza, was perhaps the western world's most exalted mathematician of the middle ages. He is best known nowadays for the discovery of the Fibonacci Series -- a series that occurs throughout nature. In this series, every new number is the result of the sum of the previous two numbers. Like this: 1,1,2,3,5,8,13,21,34 ... Many things in nature are related to Fibonacci series. No. of petals in any flower is a Fibonacci no., No. of steps in a round stair-case is a Fibonacci no., etc
