You may have already looked at how to write a general rule using variables to describe a decimal pattern with tenths. Now let's look at how to do this with patterns with hundredths.

Remember a variable is a letter that is used to represent an unknown value. Watch this video to learn more about writing rules for decimal patterns with hundredths.

Worked examples

Question 1
