What is the pattern here I can't figure it out, 2,3,5,9

2 +1 = 3

3 +2 = 5
5 +4 = 9

I bet that the next number is: 17

THANK YOU!

You're welcome.

To determine the pattern in the sequence 2, 3, 5, 9, we can look for differences between consecutive terms. Let's calculate the differences:

3 - 2 = 1
5 - 3 = 2
9 - 5 = 4

By analyzing the differences, we can see that each subsequent term is obtained by adding the next odd number to the previous term.
Let's demonstrate this:

Starting with 2:
2 + 1 = 3
3 + 2 = 5
5 + 3 = 8 (This is not the same as the given sequence, so we need to add one more odd number.)
5 + 4 = 9

Therefore, the missing term in the sequence is 8.

The complete pattern is: 2, 3, 5, 8, 9
