Use the distributive property to remove the parentheses. 2+14+26+...+ (12k-10)+(12(k+1)-10) = k(6k-4) + 12(k+1)-10 =6k²-4k+.... Then we simplify the right side of the formula. 2+14+26+...+ (12k-10)+(12(k+1)-10) = 6k²-4k+ 12k+12-10 = .... Factor the right side. 2+14+26+...+(12k-10)+(12(k+1)-10) = 6k² +8k+2=...
