Write an expression for the 15th partial sum of the series 5/3 + 4/3 + 1 using summation notation.

I don't know how to do this in the equation thing, so bear with me. It's option B:

15

E    

i=1

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

9 x 8 divided by (5-3)=36
