Member warned about not using the homework template

**Find the nth term of the sequence; ## 2, 5, 10, 17,26..........................## this is how i did it:**

**2, 5, 10, 17, 26 can form a difference of 3,5, 7,9.........**

whose nth term is 1 + 2n. now how can apply this to the original sequence to get the nth term?
