To determine

To write: The sum i=15ii+1 is in expanded form.

Expert Solution

Answer to Problem 2E

The expanded form of the sum i=15ii+1 is 12+13+14+15+16.

Explanation of Solution

Definition used:

If am,am+1,...,an are real numbers and m and n are integers such that mn, then i=mnai=am+am+1+am+2++an1+an.

Calculation:

By the above definition, the expression i=15ii+1 simplified as follows.

i=15ii+1=11+1+12+1+13+1+14+1+15+1=12+13+14+15+16

Thus, the expanded form of the sum i=15ii+1 is 12+13+14+15+16.
