A24 - A17 = - 28
=> a+23d - (a+16d) = -28
=> a + 23d - a - 16d = - 28
=> 7d = - 28
=> d = - 4
Common difference = - 4
=> a+23d - (a+16d) = -28
=> a + 23d - a - 16d = - 28
=> 7d = - 28
=> d = - 4
Common difference = - 4

a24=a+23d
a17=a+16d
so
a/q
a24-a17=-28
a+23d-a-16d=-28
7d=-28
d=-4
a17=a+16d
so
a/q
a24-a17=-28
a+23d-a-16d=-28
7d=-28
d=-4
