Question

The sum of three consecutive terms of an A.P. is 36 and their product is 1140.

Find the terms. (Consider the terms to be in descending order.)​

Answer 1

Answer:

5,12,19

Step-by-step explanation:

let a-d , a , a+d  be the 3 terms of A.P such that

   a-d + a + a+d  = 36  (given)

=> 3a = 36

=> a = 36/3

=> a= 12

also given (a-d)* a * (a+d) = 1140

           =>  (12-d) * (12) * (12+d) = 1140

           => (12-d) (12+d) = 1140/12

           => 12²- d² = 95

          =>  d² = 144 - 95 = 49

          => d = √49 = 7

=> the 3 terms are , a-d, a, a+d

                                 12-7, 12,12+7

                                 5,12,19
