-8-4-2-1-1/2-1/4-1/8
The nth term of the sequence is 3n - 2.
1/2 (By dividing -1/2)
The sequence is xn = xn-1 + 2
The next number in the sequence is 15 - the sequence goes x2, +2, -1
1 2 3 4 5 2 5 8 11 14 ... If this is the sequence, the position-to-term rule is 3n-1. However, it could be another sequence depending on the rest of the terms.
1 - 2 - 4 - 8 - 16 - 32 - 64 the sequence doubles
-8-4-2-1-1/2-1/4-1/8
The Fibonacci sequence starts with 1 and 1. However any sequence in which the first two terms are given and the rest are defined recursively as t(n) = t(n-2) + t(n-1), with n = 3, 4, ... is also known as a Fibonacci sequence. Note the "the" and "a" preceding Fibonacci sequence.
what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
The nth term of the sequence is 3n - 2.
It is the start of an arithmetic sequence.
1 , 2, 4, 7, 11 +1,+2,+3,+4
I assume that would refer to the sequence of square numbers:1, 4, 9, 16, 25, etc. To generate the sequence, you can square each number: 1 squared, 2 squared, etc.
1/2 (By dividing -1/2)
8
The sequence is xn = xn-1 + 2
