we know that
An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant. The constant is called common difference
In this problem we have an arithmetic sequence
The common difference is equal to [tex]-6[/tex]
Let
a1--------> the first term of the pattern
[tex]a1=125[/tex]
[tex]a2=a1-6=125-6=119[/tex]
[tex]a3=a2-6=119-6=113[/tex]
[tex]a4=a3-6=113-6=107[/tex]
[tex]a5=a4-6=1076=101[/tex]
the pattern is equal to
[tex][125,119,113,107,101][/tex]
