The first four terms of a sequence are shown below:

9, 5, 1, −3

which of the following functions best defines this sequence? (5 points)

a f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1
b f(1) = 9, f(n + 1) = f(n) + 4; for n ≥ 1
c f(1) = 9, f(n + 1) = f(n) − 5; for n ≥ 1
d f(1) = 9, f(n + 1) = f(n) + 5; for n ≥ 1

Option A is correct.

Step-by-step explanation:

We have been given the sequence:

9,5,1,-3

We can clearly see that the next digit is four less than the previous digit.

Here first term that is a=9

So, the function would be:

Therefore. option A is correct.

Option B and D are not correct because function is decreasing not increasing.

Option C is not correct because decreasing by 4 not 5.

A f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1
