Answer:
the correct answer is -16
Step-by-step explanation:
I took the test
The opposite of 12 is -12.
-12, -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
All you have to do is do the negative version of that same original number.
f(1)=-11
f(n)=f(1)+d(n-1)
so d=22
f(n)=f(n-1)+22
