D. 18,21,25

Answer 1

the answer for number 1 is C and the answer for number 2 is 20,24,28

Answer 2

1. 39, 49, 59 Option C

2. 20, 24, 28

Explanation:

1.

-1, 9, 19, 29...

We will find the common difference.

d = 9 - (-1) = 19 - 9 = 10

So, we add 10 to find the next term.

-1, 9, 19, 29, (29+10), (29+10+10), (29+10+10+10)

-1, 9, 19, 29, 39, 49, 59

2.

4, 8, 12, 16, ...

We will find the common difference.

d = 8 - 4 = 12 - 8 = 4

So, we add 10 to find the next term.

4, 8, 12, 16, (16+4), (16+4+4), (16+4+4+4)

4, 8, 12, 16, 20, 24, 28

that's the final answer.
