Question

2x,5x+10,10x are in A.P then value of 'x'

Answer 1

Hello friend may this help you..........

as the three terms are in AP........

Let 2x be the first term

      5x+10 be the second term

      10x be the third term

the second term is the arithematic mean of 1st and 2nd term

therefore 2x + 10x /2 = 5x+10

                12x/2 = 5x +10

                 6x - 5x = 10

                     x = 10

hence found!!!!!
