the sign shows when a lift is safe to use. Total mass of people must be 480kg or less. Fred and some other people are in the lift and their total mass is 565kg to the nearest 5kg. Fred, who has a mass of 88kg to the nearest kg, gets out of the lift. Is the lift now safe to use? Show your working.

y = x + 95

y = 42 + 95

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.

45
