Question

find three terms in AP whose sum is 36 and product is 1620​

Answer 1

Step-by-step explanation:

Let 3 term a-d a a+d

Now according to question

a-d+a+a+d = 36

So

a = 12

(a-d) a(a+d) = 1620

asquare - dsquare =. 1620/12

144 - dsquare =135

Here

d = 3

1 St term is 9

2nd term is. 12

3rd term is 15

Answer 2

Let the terms be x , x+3 and x+6

ATQ,
x + x+3 + x+6 = 36
> 3x + 9 = 36
> 3x = 27
> x = 9

> x + 3 = 12
> x + 6 = 15
