What is a function?

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given series is as follows:-

-5.5, -4.75, -4, -3.25, ...

When we use the function:-

f(n) = - 6.25 + 0.75n

f(1) = -6.25 + 0.75 x 1 = -5.5

f(2) = -6.25 + 0.75 x 2 = -4.75

f(3) = -6.25 + 0.75 x 2.25 = -4

Therefore the correct answer is option B which is the function will be

f(n) = -6.25+0.75n.
