Answer 1

Answer:

In order to find maximum value of sum we need to make sure that there us no negative term as it will reduce the value.

So, a= 50 and d= -2

nth term must be positive so

a + (n-1)d > 0

50 -2n +2 > 0

n < 26

n = 25 26th term is 0

Sum of first 25 terms = n [2a + (n-1)d]/2

= 25 [100 - 48] / 2

= 650 is the answer

Step-by-step explanation:
