Question

Sum of 3 numbers of ap is -3 and there product is 8 a-d a a+d

Answer 1

Let the three terms in AP be

a – d, a, a + d.

So, a – d + a + a + d = 3

or a = 1

Also, (a – d) (a + d) = a + 8

i.e., a2 – d 2 = a + 8

i.e., 1– d2 = 1+ 8

i.e., - d 2 = 9-1=8

i.e., d = - 4

So there will be two APs and they are : 5,4,3...
