Find maximum sum of given series
94 + 89 + 84 + 79 + ....... =
Text Solution
Verified by ExpertsThe correct answer is:
A
Let t n = first –ve term
94 + (n –1) (–5) < 0 ⇒ 94 – 5n + 5 < 0
99 < 5n ⇒ n > 19.8
n ∈ N ⇒ n = 20, 21, 22…..
⇒ t 20 , t 21 , t 22 …… are all –ve terms
S max = S 19 = 
= 
= 19 × 49 = 931
