Which of the following is not a geometric sequence?
Letter D is the correct answer
WHY?
Geometric sequencenis is one where to get from one term to the next you multiply by the same number each time. This number is called common ratio, r
This is the explaination:
For letter A
3, 5, 7, 9, 12 --- In this case its added by 2,
3 + 2 = 5 + 2 = 7 + 2 = 12 + 2 = 14 and etc
So this is a geometric sequence
For letter B
3, 6, 9, 12, 15 --- In this case its multiplied or added by
3 × 2 = 6
3 × 3 = 9
3 × 4 = 12
3 × 5 = 15
And this is geometric sequence
For letter C
3, 6, 12, 24, 48 --- In this case its multiplied by 2 and each of the numbers
3 × 2 = 6
6 × 2 = 12
12 × 2 = 24
24 × 2 = 48
In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. Similarly 10, 5, 2.5, 1.25, is a geometric sequence with common ratio 1/2.
