2. at the wava wagon wheels of chance, each student can spin two wheels of chance. the first wheel has the numbers 1, 2, and 3. the second wheel has the letters w, a, v and a (there are two sections with a). (a) make a tree diagram that lists all the possible outcomes of the compound event and their probabilities (b) when you spin both wheels, what is the probability that you get either a 2 or an a? explain.

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.
