Question

In an A. P. sum of three consecutive terms is 18 and their product is 192,find the rerms​

Answer 1

Step-by-step explanation:

let three consecutive numbers be

a,a-d,a+d

According to given condition.

a+a-d+a+d = 18

3a= 18

a= 6

According to next given condition.

a(a+d)(a-d) = 192

a(a-d)^2 = 192

(a-d)^2 = 32

a^2 +d^2 -2ad = 32

36 + d^2 - 12d = 32

d^2 -12d = -4

d^2 +d = 1/3.......(1)
