Answer:
Sally is not right
Step-by-step explanation:
Given the two sequences which have their respective
terms as following:
Sequence A. ![3n - 2](https://tex.z-dn.net/?f=3n%20-%202)
Sequence B. ![10 - 2n](https://tex.z-dn.net/?f=10%20-%202n)
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.
![3n-2=10-2n\\\Rightarrow 3n+2n=10+2\\\Rightarrow 5n=12\\\Rightarrow n = \dfrac{12}{5}](https://tex.z-dn.net/?f=3n-2%3D10-2n%5C%5C%5CRightarrow%203n%2B2n%3D10%2B2%5C%5C%5CRightarrow%205n%3D12%5C%5C%5CRightarrow%20n%20%3D%20%5Cdfrac%7B12%7D%7B5%7D)
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.
