Dillon has a bag that contains 6 red, 7 blue, 5 green, and 12 black marbles. If he reaches in with one hand and pulls out a marble and replaces it 150 times, how many times would you expect him to pull out a blue marble?

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.
