Middle term depends upon the value of n
Tn = a + (n-1)d
37 = 213 -8(n-1)
-176= -8(n-1)
22 = n-1
Therefore, n = 23
Hence there is only one middle term, (n+1)/2 th term = (23+1)/2=12 th term.
So 12th term = a + 11d = 213 + 11(-8) =125
Tn = a + (n-1)d
37 = 213 -8(n-1)
-176= -8(n-1)
22 = n-1
Therefore, n = 23
Hence there is only one middle term, (n+1)/2 th term = (23+1)/2=12 th term.
So 12th term = a + 11d = 213 + 11(-8) =125
