Find the sumofthe geometrical progression of five terms, of which the first term is 7 and the multiplier is 7.verify that the sum isthe product of 2801 and 7.

The sum of first five term of GP is 19607.

Step-by-step explanation:

We are given the following in the question:

A geometric progression with 7 as the first term and 7 as the common ration.

Sum of n terms in a geometric progression:

For sum of five terms, we put n= 5, a = 7, r = 7

The sum of first five term of GP is 19607.

Verification:

Thus, the sum is equal to product of 2801 and 7.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
