What is the arithmetic mean between 2x+3y and x-5y?

The arithmetic mean between two expressions is calculated by adding the expressions together and then dividing by 2. 

Given the expressions \(2x + 3y\) and \(x - 5y\), the arithmetic mean is:

\[
\text{Arithmetic Mean} = \frac{(2x + 3y) + (x - 5y)}{2}
\]

Now, simplify the expression inside the parentheses:

\[
(2x + 3y) + (x - 5y) = 2x + x + 3y - 5y = 3x - 2y
\]

So, the arithmetic mean is:

\[
\frac{3x - 2y}{2}
\]

Thus, the arithmetic mean between \(2x + 3y\) and \(x - 5y\) is \(\frac{3x - 2y}{2}\).
