Mathematical Induction

For the following problem:
22*7 + 2 * 7^2  ? + 2* (7)^n = (1(7)^n+1)/4
I understand that I need to first solve this for P(0). What I font understand is how the left side of the equation is equal to 2. Maybe I'm messing up the sequence of the equation or something but when I do the math I get:
(22*7 + 2 * 7^2) + (2* (7)^0) = 88
If I ignore the first portion and just do (2* (7)^0) I get 2. I am thinking maybe the math before the ellipses is just a example of a incrementing value of n and the math after the ellipses is the actual function p(). Is this correct?
