In a sequence described by a function, what does the notation f(3) = 1 mean? ОА. .
The common difference of the sequence is 3.
OB.
The first term in the sequence has a value of 3.
O c.
The common ratio of the sequence is 3.
OD.
The third term in the sequence has a value of 1.

The number inside the parentheses is the input value, the number it equals is the output value.

F(3) means the 3 would be the third term in the sequence and that would equal 1.

The answer is:

D. The third term in the sequence has a value of 1.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
