Answer 2

Solution :-

Provided :-

• 7 , 2x , 5 are in AP

Now as we know if there are three numbers in AP , let them be : a , a + d , a + 2d . Then middle term

$= \sf{ \dfrac{a + (a + 2d)}{2}}$

By using this

$\sf{ 2x = \dfrac{7 + 5}{2}}$

$\sf{ = \dfrac{12}{2} }$

$\sf{ = 6}$

Or

$\boxed{ \sf{ x = 3}}$
