Sagot :
Answer:
1. 39, 49, 59 Option C
2. 20, 24, 28
Step-by-step 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.
