It mean the variable number, n, times five.
It means: 3 times n
x-n = 1 / xn
I assume that with n(...) you mean the size of the set. It sure can; but it need not be.
n will typically mean number. It can stand for any given number, and what it stands for will depend on the problem.
"More than" is a keyword for addition. The answer to "26 more than "n"" means: 26 + n.
in a math equation "n" is normally the unidentified number in the equation and 2 is the number squared :)
zero has many functions, one of them in math is the additive identity. For any number, n, n+0=n There are many many more! Doctor Chuck

That's a u
It means: 3 times n
If this is math it is probably refering to "n" as a specified number in a key/legend

You can only answer this question if you know how many numbers there were before. (If you know how many were there after, then subtracting two gives you the number before). So suppose there were n numbers with mean x. And you add two more numbers, a and b. That means the sum of the n numbers was n*x. Sum of the n+2 numbers is n*x + a + b So the new mean is (n*x + a + b)/(n + 2)
If you call the number "n", then the expression would be "n+5".
