Answer 2

$\bold{\boxed{Hoi!}}$☺️

•We simplified the {m}^{th} and {n}^{th} term of the AP and then make an eqn. saying {m}^{th}-{n}^{th}=0.

•simplifying the equation, we take a(m-n) as common and d on the other side.

• Again we simplified and grouped the {.....}d part.

•Now, we take out the (m-n) term common from both the equation and get a+(m+n-1)d that is equal to term m+n.
