Question

Find the sum of the first 18 terms of the following sequence:

2, 6, 10 . . .

Answer 1

what is the common difference in the sequence...?

Answer 2

You're adding 4 to each number in the sequence to get the rest of the sequence. So to figure this out you can either add 4 until you get to the 18th number or you can come up with a recursive rule to make it easier on you.

Answer 3

Alrighty, thanks!

Answer 4

You're welcome.
