say the number is "y" then twice that would be 2y and plus five would be +5, so the expression is
2y + 5
ofcourse you can use other symbols instead of y.

2n+5 or 2 (n+5) depending on how it is said
twice a number, plus five is 2n + 5
twice, a number plus 5 is 2(n+5)

It isn't 2(x+5) That would make it 2x+10 wich is a completely different problem. Its 2x+5.

Think about it.
twice means 2
"a number" can be ANY LETTER you want. I will use x because it is the most popular in math.
"plus" means TO INCREASE commonly used with the symbol +, right?
Let us put it all together.
Final answer: 2x + 5

The answer to your question is as following:
2n+5
The n in this algebraic expression stands for the number that we don't know.

2n + 5 because the number is multiplied by two and add 5

2x+5
x can be any number, twice any number is 2 * the number, or 2x, and then add 5
hope it helps
