To extend a pattern with decimals, identify the rule of the pattern (such as adding or subtracting a specific decimal) and apply that rule to find the next number.

Front

What is the rule for the pattern: 0.75, 1.5, 2.25, ___?

Back

The rule is to add 0.75 to the previous number.

Front

What is the next number in the pattern: 0.25, 0.5, 0.75, ___?
