Question

If p, q ,r and s are in AP, then r - q =

Answer 1

Answer:

d ( common difference)

Answer 2

Given,

p, q, r, and s are in AP.

To Find,

r - q =?

Solution,

We can solve the question as follows:

It is given that p, q, r, and s are in AP. We have to find the value of r - q.

In an arithmetic progression, the difference between two consecutive numbers is a constant, and it's known as the common difference. It is denoted by d.

In the given A.P.,

$d = q - p$

$d = r - q$

$d = s - r$

Therefore,

$r - q = q - p = s - r = d$

Hence, r - q = q - p = s - r is equal to the common difference d.
