Question

Three numbers are such that the second is as much lesser than the third as the first is lesser than the second. if the product of the two smaller numbers is 85 and the product of two larger numbers is 115 find the middle number​

Answer 1

Step-by-step explanation:

Let x−d,x,x+d be the three numbers.

x(x−d)=85

x(x+d)=115

(1)+(2)⇒2x ^2 =200

⇒x=±10
