The Answer of Use mathematical induction to prove the formula for every positive integer n.Show all your work. $$\sum _ { i = 1 } ^ { n } i ( i + 4 ) = \frac { n ( n + 1 ) ( 2 n + 13 ) } { 6 }$$

Use Mathematical Induction to Prove the Formula for Every Positive ∑i=1ni(i+4)=n(n+1)(2n+13)6\sum _ { i = 1 } ^ { n } i ( i + 4 ) = \frac { n ( n + 1 ) ( 2 n + 13 ) } { 6 }i=1∑n​i(i+4)=6n(n+1)(2n+13)​
