What will be the maximum sum of 44, 42, 40, ... ?

**A. ** 502

**B. ** 504

**C. ** 506

**D. ** 500

**Answer : ****Option C**

**Explaination / Solution: **

The maximum sum is the sum of 44, 42,- - - - -2.

The maximum sum is the sum of 44, 42,- - - - -2.

The sum of ‘n’ terms of an AP

= n/2[2a + (n-1)d]

In this case, n = 22, a = 2 and d = 2

Sum = 11[4+21×2] = 11×46 = 506
