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)

Answer: 10.5
Step-by-step explanation:
Hope it's right!
The prediction is 193.86 lb.
Substituting 73 for x, we have:
-102.3923 + 4.0582*73 = 193.86
