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 1.83333… and so on. Assume that n is an integer variable whose value is some positive integer N. Assume also that hn is a variable whose value is the Nth harmonic number. Write an expression whose value is the (N+1)th harmonic number.
hn + 1.0 / (n + 1)
