5 Consider the arithmetic sequence below.
-9, -2, 5, 12,...
Given that the sequence is represented by the function an), determine the value of f(1) and find the common difference.
O A R1) = -2
Common difference : 7
OB.
f(1) = -9
Common difference: 7
О с.
R1) = -2
Common difference: -7
OD
R1)=-9
Common difference: -7

The right answer is:

Option OB: f(1) = -9

Common difference: 7

Step-by-step explanation:

Given sequence is:

-9, -2, 5, 12,...

Here the first number is f(1)

Common Difference:

Common difference is the difference between consecutive terms of an arithmetic sequence. It is denoted by d.

In the given sequence,

f(1) = -9

f(2) = -2

f(3) = 5

Hence,

The right answer is:

Option OB: f(1) = -9

Common difference: 7

answer: idk
