Text Solution

AI Generated Solution

To solve the problem, we need to find three numbers in Harmonic Progression (HP) given that their sum is 37 and the sum of their reciprocals is \( \frac{1}{4} \). ### Step 1: Understanding Harmonic Progression In HP, the reciprocals of the numbers are in Arithmetic Progression (AP). Let's denote the three numbers in HP as: \[ x_1 = \frac{1}{a - d}, \quad x_2 = \frac{1}{a}, \quad x_3 = \frac{1}{a + d} \] where \( a \) is the middle term and \( d \) is the common difference. ...
