Javier's swim practice is 1 1
2
hours long. The team spends
1
6
of an hour stretching before they start their practice sets. If each practice set takes
1
3
of an hour, how many sets can Javier do before practice is over?

4 sets

Step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
