Question

Which sequence is generated by the function f(n + 1) = f(n) - 2 for f(1) = 10?

Answer 1

Answer:

  10, 8, 6, 4, 2,

Step-by-step explanation:

f(1) = 10 tells you the first term in the sequence is 10. Only one answer choice has a first term of 10.

__

f(n+1) = f(n) -2 tells you that each successive term is 2 less than the previous term. The same answer choice also has that characteristic.
