Question

Which number should be added to the numbers 13,15 ,19 so that resulting numbers be the consecutive term of a H.P ? ​

Answer 1

Hii !

Solution:- suppose that x to be added then number 13 , 15, 19 so that new numbers X + 13 , 15+ X + 19+ X will be in H.P

=> (15+X) = 2 ( X + 13)(19+X) /X +13+X+19

=> X² + 31X + 240 = X² + 32X + 247

=> X = - 7Answer♻
