What is the rule to the pattern 2 3 6 11 18?

Answer 1

Oh, what a delightful pattern you've discovered! It looks like each number is increasing by adding the next odd number, starting from 1. So, 2 + 1 = 3, 3 + 3 = 6, 6 + 5 = 11, and 11 + 7 = 18. Keep exploring these patterns, my friend, and let your creativity flow!

Answer 2

The rule to the pattern 2 3 6 11 18 is that each number is obtained by adding the next odd number in sequence.

Starting with 2, the next odd number is 3, so 2 + 3 = 5.

Continuing with 3, the next odd number is 5, so 3 + 5 = 8.

Therefore, the next number in the sequence would be 18 + 7 = 25.

Answer 3

With each new term, you add a number n. This number is always odd, and increases by 2 with each term. So, starting with the first term, 2, you add n = 1 to get 3; add 3 to n = 3 to get 6; add 6 to 5 to get 11; and 7 to 11 to get 18.

Here is the pattern written out:

2 + 1 = 3

3 + 3 = 6

6 + 5 = 11

11 + 7 = 18
