Find the velocity in m/s of a swimmer who swims 110 m toward the shore in 72 s

1.527 m/s

I assume that the swimmer swims at a constant speed. Then the speed is defined as the ratio between the space and time: v=st=110m72s=1.527 m/s.

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.
