Answer:_______________

Chidambaram has saved 510 during the first month, 550 in the second month and 590 in the third month. If he continues his savings in this sequence, what will be his savings in the 21^th month

Answer: 1310

SOLUTION 1 :

Here

a = 510, d = 550 - 510 = 40

t_n = a + (n-1)d

when n = 21,

t₂₁ = 510 + (21-1}40

t₂₁ = 510 + 20x40

t₂₁ = 510 + 800 = 1310

Chidambaram has saving in the 21^th month is 1310
