Question

Two patterns start at 0. The rule in Add 3. The rule for the other pattern is Add five. Examine the number in each pattern. Explain how the numbers in each pattern are similarly

Answer 1

These 2 patterns are somewhat similar. This is because Add 3 about 5 times and you would get 15. And in for add five about 3 times and you would get 15. The same answer for both of the patterns. 
Hope it helps!
