Question

Consider the arithmetic sequence.

16, 14, 12, 10, ...

Given that the sequence is represented by the function f(n), what are the values of f(1) and the common difference?

Answer 1

Work shown below!

Explanation:

f(n) = 16 - 2(n - 1)

f(1) = 16 - 2(1 - 1)

f(1) = 16 - 2(0)

f(1) = 16

Common difference is -2
