Question

Use a number line to determine the rule in the following pattern: 9, 16, 23, 30.

A) Add 7
B) Subtract 7
C) Add 8
D) Subtract 8

Answer 1

The rule in the given pattern is to add 7.

Step-by-step explanation:

To determine the rule in the given pattern, we need to look for a consistent difference between the numbers. We can use a number line to help us identify this difference. Starting from 9, we can add the same number to each subsequent number in the pattern.

9 + 7 = 16

16 + 7 = 23

23 + 7 = 30

Since we are consistently adding 7 to each number, the rule is to Add 7.
