Best ResponseYou've already chosen the best response.1This question can be treated a an arithmetic series, with the first term being 15 + 2, the last term being 39 + 2, and the number of terms being 13  5 = 9. The required formula is \[\large S=\frac{n}{2}(a+L)\] where S is the sum of n terms, a is the first term and L is the last term.

Best ResponseYou've already chosen the best response.1No. The first term is found by plugging in the value i = 5 into 3i + 2, giving: First term = (3 * 5) + 2 = 17 The last term is found by plugging in the value i = 13 into 3i + 2, giving: Last term = (3 * 13) + 2 = 41 Do you understand?
