To be honest, it's too much of calculation,

To me finding a geometric sequence with bare hands is not that much easier, when it reach over 10^th term it's going to a night mare,

so i just find the answer for arithmetic and tick it straight away, if there are more than two same answers for the arithmetic mean i would surely get stuck, seems bit lucky today? i got the answer Right
