Question

1, 2, 3, 5, 8, 13, ...

What are the next 3 numbers in the sequence and how do I figure them out?

Answer 1

21, 34, 55

This is a very famous sequence in mathematics called the Fibonacci sequence and each value is determined by adding up the 2 previous values in the sequence.

Answer 2

For your next number being \[a_{b}\]
\[a_{b}=a_{b-1}+a_{b-2}\]

Answer 3

The sequence is usually shown as 1, 1, 2, 3, 5, 8, 13,...

The first 2 are "1" to get the sequence going. And then just add the 2 previous each time.
