Question

What is the pattern rule of 6 11 18 27

Answer 1

The pattern rule is that we add by increasing odd integers.

Explanation:

The first two numbers have a difference of 5. The next two have a difference of 7. The next two after that have a difference of 9.

5, 7 and 9 are increasing odd integers.

So, we know the next number would be 11 higher than the last.
