To find: The value of the sum i=2423i.

Expert Solution

Answer to Problem 28E

The value of the sum i=2423i is 63.5.

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 sum i=2423i expressed as follows.

i=2423i=23(2)+23(1)+23(0)+23(1)+23(2)+23(3)+23(4)=25+24+23+22+21+20+21=32+16+8+4+2+1+0.5=63.5

Thus value of the sum i=2423i is 63.5.
