Question

Find the common difference of x-y, x, x+y

Answer 1

Answer:

common difference is 'y'

Answer 2

$\huge {\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

Let x-y = A1

x = A2

and x+y = A3

therefore,

A2 - A1 => x-(x-y)

= x-x+y

= y

A3 - A2 =>x+y-x= y

A2-A1 = A3-A2 = y

So , the common difference is y ......
