Rule for Pattern R: Start with 60. Subtract 6 to get the next term.

60, 54, 48, 42, 36

Ques: write an expression you can use to generate the first five terms of Pattern R

Verified Answer :

This is an arithmetic progression. The general term of an arithmetic progression is given by:

\(a_{n}=a_{1}+(n-1)r\)
 
     Where "n" indicates the position and "r" is the ratio of progression. Therefore:

\(a_{n}=60+(n-1)*(-5) \\ \boxed {a_{n}=60+5*(1-n)}\)
