Answer: -9<x<4

Step-by-step explanation:

/ 2x +5/ < 13 , the first thing is to remove the absolute symbol , which will be

-13 < 2x + 5 < 13

solving the first part:

-13 < 2x + 5

-13 - 5 < 2x

-18 < 2x

-9 < x

solving the second part

2x + 5 < 13

2x < 13 - 5

2x < 8

x < 4

combining the two results

-9<x<4

A recursive arithmetic sequence is defined ad f(1)=6, f(n+1)=f(n)+5 for n&gt;1. The first four terms of the sequence are shown i
Dennis_Churaev [7]
Write the first few terms of the sequence.
f₁ = 6
f₂ = f₁ + 5 = 11
f₃ = f₂ + 5 = 16
f₄ = f₃ + 5 = 21
and so on

The sequence is
6, 11, 16, 21, ...,
This is an arithmetic sequence with a common difference of 5.

In function notation, the sequence is
f_{n+1} = 6 + 5n, \\ \, n=0,1,2, \, ...,

This represents the equation of a straight line with n as the independent variable and f as the dependent variable.
The slope is 5. 
A graph of the line is shown below.

Answer:
The sequence is f_{n+1} = 6 + 5n, \,\, n=0,1,2, \, ...,
The slope is 5.
