Nick and Kareem are running a 100 meter race against each other. Nick agrees he will get a 10 m head start and he runs at a rate of 21 meters every 2 seconds. Kareem begins at the starting
line and runs at a rate of 26 meters every 2 seconds second.

x = 25/2304

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.

47
