We can use what we know about patterns with numbers to help us determine if a number is even or odd.

Write the next number in the pattern:

2, \,4, \,6, \,8, \,10, \,12, \,⬚

Worked Solution

Idea summary

To find the next number with an increasing pattern, we need to find how much is added each time and add it to last given number.

What are even and odd numbers? How can we determine if a number is even or odd? Let's find out.
