Find the sum of the following series.
∑n=112(2n+3)
To find the sum of the series, we need to add up the terms from n=1 to n=12.
∑n=1-12 (2n+3) = (2(1)+3) + (2(2)+3) + ... + (2(12)+3)
Simplifying each term, we get:
= 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25 + 27
Adding up all the terms, we get:
= 164
Therefore, the sum of the series is 164.
