-4/3, -1 , -2/3......41/3. Find the sum of two middle most term of the A.P

to find the sum of two middlemost terms we should first find no. of terms.

using nth term =a+(n-1)d

               41/3=-4/3+(n-1)1/3

                45=n-1

               n=46

           so there will be two middle terms

            also we know that

      t1+t46=t2+t45=.................=t23+t24

     so sum of two middle terms =t1+t46=37/3
