The average speed of one race car driver was 151.89 miles per hour, while the average speed of another driver was only 142.48 miles per hour. how much faster was the first driver

9.41 miles per hour.

Step-by-step explanation:

Since, Here The average speed of one race car driver, miles per hour

And, The average speed of another driver, miles per hour

Thus,  first driver is faster than second driver ( because his speed is greater than that of second)

And, He is faster than second by the speed =  

= 151.89-142.48= 9.41 miles per hour.

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.
