Answer:
c 1, 2, 4, 8
Step-by-step explanation:
It can work well to look at the first differences.
a: 4 -2 = 2; 6 -4 = 2 ⇒ differences are 2, 2, 2
b: differences are 0, 1, 1
c: differences are 1, 2, 4
d: differences are 2, 2, 2

Sequences 'a' and 'd' have common differences that are constant. These are arithmetic sequences. Sequence 'b' is of no named type.
Sequence 'c' has first differences that have a common ratio, the same as the sequence itself. This is an indication the sequence is geometric. The ratios of values are 2/1 = 2; 4/2 = 2; 8/4 = 2, so the terms have a common ratio.
Sequence c is a geometric progression.
Answer:
3/13
Step-by-step explanation:
First you need to know what a reciprocal is. Is the fraction flipped.
Steps:
1. turn 4 1/3 into an improper fraction
4x3 +1 = 13
13/3
2. Flip it
13/3 ---> 3/13

B, because they go by fives
I believe your answer is 4 4/9 as a mixed fraction but it can also be 40/9. Hope this helps :)
