Question

15×2

Answer 1

By rows

15, 13, 11, 9, 7, 5, 3, 1

 

How many cans in the fifth row?

Answer 2

I assume you meant to say that each row has 2 fewer cans than the row below it, and you want to know how many cans are in the 5th row from the bottom.

 

Bottom row (row 1): 15 cans

Next row (row 2):  15 - 2 = 13 cans

Row 3:  13 - 2 = 11 cans 

Row 4:  11 - 2 = 9 cans

Row 5:  9 - 2 = 7 cans
