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
