Question

Which represents the explicit formula for the arithmetic sequence on = 7 - 3(n - 1) in function form?
f(n) = 3n - 6
B f(n) = -3n - 6
f(n) = 3n - 10
D f(n) = -3n + 10

Answer 1

Answer:

Step-by-step explanation:

All this question is asking you to do is distribute through the parenthesis to simplify. Doing that gives us

f(n) = 7 - 3n + 3 and

f(n) = 10 - 3n or

f(n) = -3n + 10, choice D.
