Find the nth term of this sequence:

5, 10, 15, 20, 25 ...

The sequence advances by adding 5 to the previous number.

So the nth term is 5*n, given n>0 and goes to infinity.

Why?

Let's look at this:

n=0 means first number in the sequence should be 0. This is wrong.

n=1 - next number is 5.

n=2 - next number is 10.

The answer would be 40
