Question 3.
List the totals from Problem 1.
List the totals from Problem 2.
Are the numbers you have listed even or not even?
Explain in what ways the numbers are the same and different.
The totals from problem 1 are 2, 4, 6, 8, 10
The totals from problem 2 are 12, 14, 16, 18, 20
The number I have listed is even
In both sets of numbers have the same number of ones, but the numbers in problem 2 have one more than the numbers in problem 1.
