It'd be easier to do #18 if y ou were to break it up:

14* (first term + 14th term)
Sum from n=1 to 14 of n = S = ---------------------------------
14 2

14(1+14)
= ---------------- = 7(15) = 105
2

The sum of twice that is 210. The sum of "1 from n=1 to n=14" is just 14.

The final sum is 210 + 14 = 224 (answer)
