The manager at a supermarket arranged 10 rows of cans. He put 2 cans in the first row, 4 cans in the second row, and 6 cans in the third row. The manager continued to add 2 cans to each new row.
a. How many cans did the manager put in the fifth row? Show or explain how you got your answer.
b. What is the total number of cans the manager arranged in all 10 of the rows? Show or explain how you got your answer.
c. Describe the relationship between the row number and the number of cans in the row.
Answer (2)
a)
2, 4, 6, 8, *10
The fifth row contains 10 cans.
b)
2+4+6+8+10+12+14+16+18+20=110
c)
2*Row=Number Of Cans
When Row=1, Number Of Cans=2.
When Row=5, Number Of Cans=10.
When Row=10, Number Of Cans=20.
In the fifth row, the manager put 10 cans. The total number of cans arranged in all 10 rows is 110. The number of cans in each row follows the pattern where the number of cans equals 2 times the row number.
