1.three numbers are in AP and their sum is 15. If 8,6,4 are added to them respectively,they form a GP.The numbers are.
Please tell me the solution and method of solving this type of questions using this formula for Ap:(a-d),a, (a+d) and for GP:a/r,a,ar
The option for the above question is :A)2,6,7 B)4,6,5 C) 3,5,7
The above is question of AP and GP.
