Answer:
Option A is the correct answer.
Step-by-step explanation:
0.5, 0.25, 0, –0.25
.....
The above series is an example of arithmetic progression.
First term of this AP, a = 0.5
Common difference, d = -0.25
We have equation for n th term = a + ( n-1)d
Substituting
equation for n th term = f(n) = 0.5 + (n-1)x -0.25
f(n) = 0.5 + (n-1)x -0.25 = 0.75 - 0.25 n
Changing n with x we will get
f(x)= 0.75-0.25x
Option A is the correct answer.
