3n + 5

Step-by-step explanation:

3n + 7 - 2

3n is a variable.

7 and 2 are numbers.

Variables can be added with variables.

If variables are added with numbers, it remains constant ( and vice - versa ),

That is.

3n + 7 = 3n + 7

When the value of n is given, then the result of " 3n + 7 " will be a number.

In this question, the value of n is not given.

Numbers can be added or subtracted with numbers. The result will be a number.

7 - 2 = 5

So,

the answer is 3n + 5

answer: -8.2562234e+13
