150 people

Step-by-step explanation:

First, look over the chart and find the rows that have listed as 26 - 30 and 31 - 35.

Find out how high the row goes by looking at the number on the side of the gram.

26 - 30 goes to 60

31 - 35 goes to 90

Then add the 2 numbers together and you will find your total

60 + 90 = 150 people

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.
