Answer 2

$\boxed{\boxed{\underline{\huge{\bold{Answer}}}}}$

if k,2k,3 are in Ap then thier common difference are equal

so consider

k=a1

2k=a2

3=a3

now we have

$a2 - a1 = a3 - a2 \\ 2k - k = 3 - 2k \\ k = 3 - 2k \\ k + 2k = 3 \\ 3k = 3$

$\boxed{\boxed{\underline{\huge{\bold{\mathfrak{\green{k=1}}}}}}}$
