Answer:_______________

Kumar has saved 670 during the first month, 740 in the second month and 810 in the third month. If he continues his savings in this sequence, what will be his savings in the 19^th month

Answer: 1930

SOLUTION 1 :

Here

a = 670, d = 740 - 670 = 70

t_n = a + (n-1)d

when n = 19,

t₁₉ = 670 + (19-1}70

t₁₉ = 670 + 18x70

t₁₉ = 670 + 1260 = 1930

Kumar has saving in the 19^th month is 1930

when n = 18,

t₁₈ = 660 + (18-1}60

t₁₈ = 660 + 17x60

t₁₈ = 660 + 1020 = 1680

Raj has saving in the 18^th month is 1680
