This equation shows how the accuracy of Nellie's watch is related to how long it's been since she last set it. s = 5d

The variable d represents the number of days passed since Nellie last set her watch, and the variable s represents how many seconds behind the watch is. How many days has it been since Nellie last set her watch if the watch is 10 seconds behind?

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.

1

step-by-step explanation:

it's the only multiple of both and the least

ab will be equal to
