Question

If 18, x,y-3are in A.P the value of x+y​

Answer 1

Step-by-step explanation:

Hey mate !!

Here's the answer !!

We know that in an AP, the common difference is same between all the terms in that AP.

So,

=> x - 18 = y - x = - 3 - y

=> x - 18 = - 3 - y

Transposing " y " to the RHS, we get,

= x + y = - 3 + 18

=> x + y = 15

Hope my answer helped !!
