Sir I can't understand the purpose of geometric mean means why we can't use arthmatic mean instead of this ..What exactly the geometric mean is?

This is completely wrong I'm afraid. The true geometric mean of this progression, plus 1, and then raised to the fourth power (GM+1)^4, should be equal to 1.04*1.02*1.02*1.02. (1.04*1.02*1.02*1.02) = 1.10365632 [to 8 decimal places] Your GM of 2.378% gives (1+0.02378)^4 = 1.098567039 1.10365632 ≠ 1.098567039 , so this value is not the true GM. (NB not a rounding error, all calculations made in full) The true GM is given by ({1.04*1.02*1.02*1.02}^(1/4) - 1) = 0.02496365 = 2.496365% We can check this result: (GM + 1)^4 = 1.10365632 [to 8 decimal places] , as required, for GM = 0.02496365 .
