Difference d=−41−(−49)=−33−(−41)=8

Sum, S

n

=

2

n

[2a+(n−1)d]

Since the series is made by combining two terms (i.e, (1−50),(4−45)...) therefore we will have to take the sum of the first 15 terms for the newly formed series to get the sum of first 30 terms of the given series.

∴S

15

[2×(−49)+(15−1)(8)]=105
