Answer 2

Answer:

The answer to this question is 13.

Step-by-step explanation:

This is known as the Fibonacci sequence. It is solved by adding the 2 numbers in the sequence to get the next (for example, 0,1,1,2,3,5 is 0+1=1,1+1=2, 1 + 2=3 and so on). The Fibonacci sequence is endless, adding the following numbers, going on forever. Other mathematics similarities that are also infinite is 1/3, pi, phi, and others.
