Zachary collects cans for the recycling club.
On the first day, he found 4 cans.
On the second day, he found 9 cans.
He found 14 cans on the third day.
If this pattern continues, how many cans do you
think Zachary will find on the seventh day?
Zachary collects 4 cans on the first day, 9 cans
on the second day, and 14 cans on the third
day.
This sequence is represented by
4, 9, 14, ......
This forms an AP.
First-term, a = 4
common difference, d = (9 - 4) = 5
On the 7th day,
a7 = a + 6d = 4 + 6 * 5 = 34
Hence, He found 34 cans on the 7th day.
