Question

Find the value of x for which(8x+4),(6x-2), and (2x+7) are in A.P

Answer 1

Hey there !!!

____________________________________________________

If a,b,c are in A.P 

      b=a+c/2

According to question 8x+4,6x-2,2x+7 are in A.P

         6x-2=(8x+4+2x+7)/2

         6x-2=10x+11/2

         2(6x-2)=10x+11

          12x-4=10x+11

           12x-10x=11+4

               2x=15

               x=15/2=7.5
