### LANGUAGE: Visual Basic

### CHALLENGE:

In mathematics, the Nth harmonic number is defined to be 1 + 1/2 + 1/3 _ 1/4 + … + 1/n.

So, the first harmonic number is 1, the second is 1.5, the third is 1.833… and so on.

Assume also that hn is a double variable whose value is the Nth harmonic number.

Write an expression whose value is the (N+1)th harmonic number.

### SOLUTION:

hn + 1.0 / (n + 1)
