Answer 1

$\bigstar$$\boxed{\huge{\red{\mathfrak{Answer}}}}$$\bigstar$

_________________________

❥︎ $\mathtt{a_{7} \longrightarrow 4\times a_{2}}$

❥︎ $\mathtt{a+6d \longrightarrow 4(a+d)}$

❥︎ $\mathtt{4a - a \longrightarrow 6d - 4d }$

❥︎ $\mathtt{3a \longrightarrow 2d }$

❥︎ $\mathtt{\frac{a}{d} \longrightarrow \frac{3}{2}}$

❥︎ $a : d = 3 : 2$

a → 3

d → 2

A.P → 3 , 5 , 7 , 9
