Idea summary

To continue patterns with decimals, we look for how our numbers are changing. Then we can continue the pattern.

This video looks at some pattern concepts where we cross over whole number values, and places.

Consider the following pattern. 1.8, \, 1.5, \, 1.2, \, ⬚, \, ⬚, \, ⬚

a

What is the pattern?
