Question

Marissa uses this rule to create a pattern. Start with the number 108 and subtract 13

Answer 1

Answer:

$108 - 13n$ is the pattern

Step-by-step explanation:

We have that,

Initial number for the rule, $a_{1}$ = 108

The next number is obtained by subtracting 13 i.e. $a_{2}$ = 108 - 13

So, third number is $a_{3}$ = (108 - 13) - 13 = 108 - 2×13

Then, fourth number is $a_{4}$ = (108 - 2×13) - 13 = 108 - 3×13

Going on, we get the pattern = $108 - 13n$.

Hence, using the given rule, we get the pattern to be $108 - 13n$.
