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

Expert Answer:
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
