Question

If the second term of an ap is x-y and 5th term is x+y then find its first term

Answer 1

I hope this is correct

Answer 2

$\frac{2y}{3\\}$Answer:

a = $\frac{x-5y}{3}$

Step-by-step explanation:

a + 4d = x + y                ----------------(1)

a + d = x - y                   ----------------(2)

subtracting equation 2 from 1

we get,

           =   3d = 2y

           =   d = $\frac{2y}{3}$

from equation (1)

a = x - y - 2y/3

a+  x-5y/3
