Sn = n^2 + 5n + 94 and K = S6 – S5 + S4 – S3 - S2 + S1. What is the value of K?	Select the correct option:  A) 67  B) 20  C) 45  D) 41  E) 36
I used brute force for this question:   S6: 36+30+94=160   S5: 25+25+94=144   S4: 16+20+94=130   S3: 9+15+94=118   S2: 4+10+94=108   S1: 1+5+94=100   S6-S5+S4-S3+S2-S1= 16+12-8=
