Which of these is not a geometric sequence? 3, 6, 12, 24, ... 250, 50, 10, 2, .... 5, 15, 45, 135, ... 4, 12, 20, 28, ...

Answer:
4, 12, 20, 28
Step-by-step explanation:
The 1st one has the pattern of 2x
3 * 2 = 6
6 * 2 = 12
12 * 2 = 24
Everything in this sequence is true
The 2nd one has the pattern of divided by 5
250/5 = 50
50/5 = 10
10/5 = 2
The 2nd one is true
The 3rd one has the pattern of 3x
5 * 3 = 15
15 * 3 = 45
45 * 3 = 135
The 3rd one is true
The 4th one however, I don't seem to see a pattern
4 * 3 = 12
But...
12 * 3 ≠ 20
20 * 3 ≠ 28
Which makes it false
Hope this helps!!!
