What is the sum of the arithmetic series below?

15

E Fn=4i-1

i=1

A. 930

B. 868

C. 434

D. 465

Your question transforms to finding the following sum : 3 + 7 + 11 + 15 ... upto 15 terms

Use formula for sum of an AP series

S = (n * (2a + (n - 1) d)) / 2

n - > no of terms in AP series, so n = 15

a - > first term in series, so a = 3

d - > common difference, so d = 4

Put all values for a, n, d and you will get the sum.
