If you rounded it it would be 4.6
Since the <u>difference between consecutive terms is not constant</u>, the sequence is not arithmetic.
In an arithmetic sequence, the <u>difference between consecutive terms is constant</u>, called common difference d.
A recursive formula is given by:

In which
is the first term.
In this problem:
- The terms are: 100, 135, 149, 165, 188.
- 135 - 100 = 35, 149 - 135 = 14, that is, the differences are not constant, so this is not an arithmetic sequence.

First, subtract 68 from 57. Which equals 11. Then add 11 + 69. That equals 80.
Use the slope formula
(y₂ - y₁)/(x₂ - x₁)
Let (0,2) = (x₁, y₁)
Let (3,0) = (x₂, y₂)
Plug into corresponding variables
(0 - 2)/(3 - 0) = -2/3
-2/3 is the slope of the line given
-------------------------------------------------------------------------------------------------------
To find the perpendicular line, flip the slope around and change the sign.
-2/3 becomes 3/2
The perpendicular line's slope is 3/2
