You can put this solution on YOUR website! which of the sequence are arithmetic which are geometric and which are neither
1,3,5,7,9
d = 2 so arithmetic
--------------------------
3,6,12,24,48
r = 2 so geometric
--------------------------
9,13,17,21,25,29
d = 4 so arithmetic
--------------------------
