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
