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. 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.

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
