Question

The first four terms of a sequence are shown below:

6, 2, -2, -6

Which of the following functions best defines this sequence?

Answer 1

f(1) = 6, f(n + 1) = f(n) + 4; for n ≥ 1
f(1) = 6, f(n + 1) = f(n) - 2; for n ≥ 1
f(1) = 6, f(n + 1) = f(n) - 4; for n ≥ 1
f(1) = 6, f(n + 1) = f(n) + 2; for n ≥ 1

Answer 2

how much do you add or subtract to 6 to get 2?

Answer 3

4

Answer 4

add or subtract?

Answer 5

subtract

Answer 6

so -4

Answer 7

how about from 2 to -2?

Answer 8

and -2 to -6?

Answer 9

subtract 4

Answer 10

so
f(1) = 6, f(n + 1) = f(n) - 4; for n ≥ 1
