They don't. If you add two positive numbers, the result will always be a larger positive number. You are probably doing this with a computer program; in this case, you may get a numeric overflow. Precautions should be taken to detect this overflow, and give appropriate error messages. Alternately, you can use a data type that supports larger numbers - for example in Java, use long instead of int, or for even larger numbers, use the BigInteger class, which supports an arbitrary number of digits (at the expense of slower processing).

Negative numbers do not naturally occur in the Fibonacci sequence. The sequence begins with 0 and 1, and each subsequent term is obtained by summing the two preceding terms. If negative numbers seem to be appearing after 23 terms, it is likely due to a mistake or misinterpretation in the calculation or observation.

A Fibonacci number series is like the example below, 1,1,2,3,5,8,13,21,34,55,89,144,233,377,610...... and so on in general Fibonacci numbers are just the previous two numbers added together starting with 1 and 0 then goes on forever.

The Fibonacci sequence is a series of numbers That was discovered by an Italian mathematician called Leonardo Pisano. Sequences are a patter of numbers.

37 is not in the Fibonacci number series, but is the sum of two Fibonacci numbers, 34 and 3. Fibonacci numbers are with 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, etc.

There is no upper bound to the sum of the numbers in the Fibonacci sequence; both the last number in the series and consequently the sum of all these numbers can be made as large as desired by continuing the series to sufficiently many numbers.

Each term of the series is the sum of the two terms before it.

The Fibonacci numbers is a series of numbers that are found in nature and other things. The series goes 0,1,1,2,3,5,8,13,21 and so on. You just add the last two numbers in the series. 0+1=1, 1+1=2, 2+1=3, and so on.

A Fibonacci number, Fibonacci sequence or Fibonacci series are a mathematical term which follow a integer sequence. The first two numbers in Fibonacci sequence start with a 0 and 1 and each subsequent number is the sum of the previous two.
