Answer:
-2497
Step-by-step explanation:
We are given an arithmetic series with the following terms:
First term, = -40
Common difference, d = -7
Number of terms, n = 22
To find out: Sum of n terms, where n is 22
We know that Sum of n terms in an arithmetic series is given as:
Putting the values in the formula:
So, the sum of 22 terms is <em>-2497</em>.
