Mike is giving roses to some children at a carnival. he has 7 red roses, 8 yellow roses, and 9 white roses. if mike selects a rose randomly without looking, what is the probability that he will give a white rose to the first child and then a yellow rose to the second child

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.
