Answer:
Both Ivy and Andrey
Step-by-step explanation:
-100, -50, 0, 50 is an arithmetic sequence, because it has a common difference:
-50 − (-100) = 50
0 − (-50) = 50
50 − 0 = 50
The first term is -100 and the common difference is 50, so:
f(n) = -100 + 50 (n − 1)
Simplifying:
f(n) = -100 + 50n − 50
f(n) = -150 + 50n
So both Ivy and Andrey are correct.
