Prove the following statement. Assume that all sets are subsets of a universal set U. For all sets A and B, if ⊆ B then A ∪ B = U.
Hint: Once you have assumed that A and B are any sets with
Ac ⊆ B, which of the following must you show to be true in order to deduce the set equality in the conclusion of the given statement? (Select all that apply.)

two data sets with the same median will not have the same varaibility

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

35 is an outlier
