* The nth term of sequence A is 3n − 2 The nth term of sequence B is 10 − 2n Sally says there is only one number that is in both sequence A and sequence B. Is Sally right? You must explain your answer.

Sally is not right

Step-by-step explanation:

Given the two sequences which have their respective terms as following:

Sequence A.

Sequence B.

As per Sally, there exists only one number which is in both the sequences.

To find:

Whether Sally is correct or not.

Solution:

For Sally to be correct, we need to put the terms of the respective sequences as equal and let us verify that.

When we talk about terms, here is a whole number not a fractional number.

But as per the statement as stated by Sally is a fractional number, only then the two sequences can have a number which is in the both sequences.

Therefore, no number can be in both the sequences A and B.

Hence, Sally is not right.
