Questions & Step-by-Step Solutions

Which of the following statements is true regarding harmonic progressions?
  • Step 1: Understand what a harmonic progression (HP) is. It is a sequence of numbers where the reciprocals of the terms form an arithmetic progression (AP).
  • Step 2: Recall what an arithmetic progression is. In an AP, the difference between consecutive terms is constant.
  • Step 3: If you have a harmonic progression like a, b, c, then the reciprocals are 1/a, 1/b, 1/c.
  • Step 4: Check if the reciprocals (1/a, 1/b, 1/c) form an arithmetic progression. This means that (1/b - 1/a) should equal (1/c - 1/b).
  • Step 5: Conclude that since the reciprocals of the terms in a harmonic progression do indeed form an arithmetic progression, the statement is true.
