Step-by-step explanation:
Given: Sequence of number:- 1, 2.5, 4, 5.5, 7, ....
First we find the formula of the sequence
First term, a₁=1
Second term, a₂=2.5
Common difference, d = a₂ - a₁
d = 2.5 - 1 = 1.5
Formula:
So, function of the sequence will be
This is equation of straight line. Now, we draw the graph of function.
Make table of n and f(n)
n : 1 2 3 4 5
f(n): 1 2.5 4 5.5 7
Plot the points on graph. Please see attachment for graph.
Domain of function: n≥1
Because sequence is start from 1.

Answer: Third option
Step-by-step explanation:
For this exercise it is important to remember the following:
1. By definition, the Associative property of addition states that it does not matter how you grouped the numbers, you will always obtained the same sum.
2. The rule for the Associative property of addition is the following (given three numbers "a", "b" and "c"):
Knowing the information shown before, you can identify in the picture attached that the option that illustrates the Associative property of addition is the third one. This is:
As you can notice that you will always get the same result:
