Write the series -25-22-19+ for 14 terms using summation notation

The correct answer option is a. 14∑1 (-28+3n)

Step-by-step explanation:

The summation notation for the given series is 14∑1 (-28+3n) where (the index of summation or the lower limit of summation) is 1 and (the upper limit of summation) is 14.

Putting in the values of the limit from 1 to 14 in the notation to get the first 14 terms of the series:

Therefore, first option is the correct one.
