Hi good morning: I have a question with the following:

In a university in 2002 had 10,400 students enrolled, and 2007, 13200.

Estimating how many there were: 2003, 2005, 2000, 2010 and 2040.

**SOLUTION:**
For the linear interpolation formula:

And replacing the values:

For the year

**2003:**
For the year

**2005:**
And so on.

But when calculating the year 2040 the output is:

Here is my question. Is that correct?

Greetings and apologies if this is not the forum suitable, to me is an ongoing problem of mathematical analysis.
