Answer:

C

Explanation:

Ivy says:

f(1) = -100

  • f(n) = -100 + 50( n - 1 )
  • f(1) = -100 + 50( 1 - 1 )
  • f(n) = -100 + 50(0 ) anything times 0 is 0!
  • f(1) = -100

You do that with the other numbers in the sequence. 2 = -50, 3 = 0 and so on

When you to n as 1, 2, and 3 they seem to all check out. So Ivy is right!

Andrey says:

  • f(1) = -100
  • f(1)= -150 +50(1)
  • f(1) = -150 + 50
  • f(1) = -100

That's a little suspicious don't you think that both answers are right..

Essentially they are both the same equation!

So let's simplify Ivy's equation!

f(n) = -100 + 50( n - 1 )

f(n) = -100 + 50n - 50

f(n)= -150 +50n

Which is basically Andrey's equation and they both seem to be right for the sequence! So both of them are right!
