Question

Write the correct number in the given boxes from the following $A.P$
$2,-,26$

Answer 1

Let $2nd$ term $=x$

So A.P is

$2,x,26$

Since it is an AP,

Common difference is same

$\therefore$ second term $-$ first term $=$ third term $-$ second term.

$x-2=26-x$

$x+x=26+2$

$2x=28$

$x=\frac{28}{2}$

$x=14$

So, the AP is $2,14,26$
