[a]1. Homework Statement [/b]
Evaluate:
12
[tex]\sum[/tex] (6n + 1)
n=5
2. The attempt at the solution
So, how do i go about doing this? I tried finding the first three numbers of the series to find the difference by substituting n = 5,6,7 and then use the Sum formula S = n/2[2a + (n-1)d]. But the answer turned out to be wrong. The correct answer to this is 416.
