Question 22

Multiple Choice

Use mathematical induction to solve for all positive integers n. i=1ni(i+4) =?\sum _ { i = 1 } ^ { n } i ( i + 4 ) = ?


A) n(2n+13) 6\frac { n ( 2 n + 13 ) } { 6 }
B) n(n+1) (2n+13) 4\frac { n ( n + 1 ) ( 2 n + 13 ) } { 4 }
C) n(n+1) (n+13) 6\frac { n ( n + 1 ) ( n + 13 ) } { 6 }
D) n(n+1) (2n+13) 6\frac { n ( n + 1 ) ( 2 n + 13 ) } { 6 }
E) n(n+1) (2n+13) 2\frac { n ( n + 1 ) ( 2 n + 13 ) } { 2 }
