Question

Describe the pattern 2,6,12,20,30 Describe the pattern 2,6,12,20,30

Answer 1

To describe the pattern, maybe it would be helpful to find the difference between terms. We do as follows:

30 - 20 =  10
20 - 12 =   8
12 - 6   =   6
6 - 2     =   4

As we can see the pattern's difference is a factor of two. The differences are divisible by 2. Hope this helps. Have a nice day.
