Does 31 fall into the Fibonacci sequence?

Answer 1

No,

because

1 2 3 5 8 13 21 34

this is part of the fibonacci sequence and as you can see it goes straight on to 34 and doesn't have 31

Answer 2

No, 31 is not part of the Fibonacci sequence. The Fibonacci sequence starts with 0 and 1, and each subsequent number is the sum of the two preceding numbers (e.g., 0, 1, 1, 2, 3, 5, 8, 13, 21, ...).
