Answer
Answer (as printed): E
Explanation
2nd term = (1st term × 1 + $1^2$) = 1 × 1 + $1^2$ = 2; 3rd term = (2nd term × 2 + $2^2$) = 2 × 2 + $2^2$ = 8; 4th term = (3rd term × 3 + $3^2$) = 8 × 3 + $3^2$ = 33; 5th term = (4th term × 4 + $4^2$) = 33 × 4 + $4^2$ = 148; 6th term = (5th term × 5 + $5^2$) = 148 × 5 + $5^2$ = 765. 760 is wrong.
