Sn = n^2 + 5n + 94 and K = S6 – S5 + S4 – S3 + S2 – S1+S0. What is the value of K? Pick: A) 67 B) 130 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   S0: 0+0+94=94   S6-S5+S4-S3+S2-S1+S0= 16+12+8+94=
