Step-by-step explanation:

a=-4/3. d=-1+4/3. an=13/3

=1/3.

an=a+(n-1)d

13/3 = -4/3+(n-1)1/3

13/3+4/3=(n-1)1/3

13+4/3=(n-1)1/3

17*3/3=(n-1)

n-1=17

n=17+1

n=18,which is even

middle most term=(n/2)th term and (n+1/2)th term

=(18/2) th term and (n+1/2)th term

9th term and 10th term

so,the middle most term is a9 and a10

a9 =4/3

a10= 5/3

a9+a10

4+5/3

=9/3

= 3 is the answer
