8x8x+1

Explanation:

It can be seen that each successive term is bigger than the previous one by xx. This is the common difference . It can also be found by subtracting a term from the next one. 3x+1 - (2x+1)3x+1−(2x+1) results in xx.
This means that the number of a term is the same as the co-efficient of xx. 1 is added each time. The 8th term will be 8x8x+1
