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!
