If 8 harmonic means are inserted between two numbers \( a \) and \( b(ab) \) such that arithmetic mean of \( a \) and \( b \) is \( 5 / 4 \) times equal to geometric mean of \( a \) and \( b \) then \( \left(\frac{\mathrm{H}_{8}-\mathrm{a}}{\mathrm{b}-\mathrm{H}_{8}}\right) \) is equal to.https://bit.ly/YTAI_PWAP https://www.pw.live
