To write: The sum 3+4+5+6+7 in sigma notation.

Expert Solution

Answer to Problem 12E

The sum 3+4+5+6+7 expressed in sigma notation as i=37i.

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:

Here, the sum 3+4+5+6+7 is the sum of 5 numbers and the number is of the form i, where i varies from 3 to 7.

Thus, by the above definition the sum 3+4+5+6+7 expressed as follows.

3+4+5+6+7=i=37i

Thus, the sum 3+4+5+6+7 expressed in sigma notation as i=37i.
