What is the sum of the series?

The sum of given series is 44

Solution:

Given that we have to find the sum of the series

Given series is:

Substitute k = 1 to k = 4 to find the sum of the series

When k = 1:

When k = 2:

When k = 3:

When k = 4:

Therefore, the sum of series is given as:

Thus the sum of series is 44

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
