Answer:
No. 6 is
5, 15, 45, 135,405
Step-by-step explanation:
5x3=15
15x3=45
45x3=135
135x3=405
Sol:
To find the common ration, we need the formula r = or or and so on..
First we'll find the second,
r =
r = 2,
Now that we found the common ratio we can,
3 x 2 = 6 (the second term!)
6 x 2 = 12
12 x 2 = 24
24 x 2 = 48 (the fifth term!)
So, 3, 6, 12, 24, 48
By using the same formula,
r = 7
Now,
2 x 7 = 14
14 x 7 = 98 (The third term!)
98 x 7 = 686
686 x 7 = 4802 (the fifth term!)
So, 2, 14, 98, 636, 4802
