Answer 2

$\displaystyle\huge\red{\underline{\underline{Solution}}}$

TO CHOOSE THE CORRECT OPTION

If p, q and r are three consecutive terms of an AP whose common difference is d,

then the value of r - p is

• d

• 2d

• 3d

• 4d

CALCULATION

Since p, q and r are three consecutive terms of the Arithmetic progression with common difference d

So

First term = p

Second Term = q = p + d

Third Term = r = p + 2d

Hence

$\sf{ r - p}$

$= \sf{ p + 2d- p}$

$= \sf{ 2d}$

RESULT

$\boxed{ \sf{ \: r - p = 2d\: \: }}$
