as its arithmetic sequence then common difference will be same ..
therefore
therefore by formula
a + c = 2b
that is 24 + p^2 = 2p
p^2 - 2p + 24

here first term=a= 24
common difference=d= p-24
we know that third term= a3 = p^2
therefore a3=p^2
=> a +2d = p^2
=> 24 + 2(p-24) = p^2
=> 24 +2p - 48 = p^2
=> 2p - 24 =p^2
=> p^2 -2p +24 =0
You can solve the quadratic equation now.
Hope this helps:)
