Answer 2

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

FORMULA TO BE IMPLEMENTED

If $a, a+d, a + 2d, a+3d, a+ 4d,............$

is an Arithmetic Progression

Then First Term = a

Second Term = a + d

Common Difference

= Second Term - First Term = (a + d) - a = d

CALCULATION

The give Arithmetic Progression is

9 , 13 , 17 , 21 , 25 ........

Then First Term = 9

Second Term = 13

Common Difference

= Second Term - First Term = 13 - 9 = 4

So next term

= 25 + 4

= 29

সুতরাং পরের সংখ্যাটি হল 29
