Question

If p, q and r are three consecutive terms of an AP whose common difference is d, then the value of r-p is _______.
(a) d
(b)2d
(c)3d
(d)4d​

Answer 1

Answer:

2d

Step-by-step explanation:

to understand this let us take this example;

suppose the AP is 2,4,6....

here the difference is 2 and our r is 6 and p is 2

Now, 6-2 i.e, (r-p)

gives us 4 that is our 2d
