You know the numbers must be consecutive (which means right next to each other) so it can't be the first one. Therefore 21 and 23 is the least possible pair of integers.

Let A = {15, 25, 35, 45, 55, 65} and B = {25, 45, 65}. What is A ∩ B?
NemiM [27]

Answer:

A∩B={25, 45, 65}

B is a proper subset of A:

B⊂A

Step-by-step explanation:

A∩B means the intersection of the set A and the set B. In other words, is the set of elements contained in these both sets.

Given the set A and the set B:

A ={15, 25, 35, 45, 55, 65}

B ={25, 45, 65}

You can indentify that the numbers common in both sets are: 25,45 and 65.

Therefore you get:

A∩B={25, 45, 65}

Since all elements of B are in A, and A contains elements that are not in B, then B is a proper subset of A:

B⊂A
