The set = 50,52,54,56,58,........,492,494,496,498,500
Number of terms =
Here,
Number of terms (n) = 225+1 = 226
Median = Average of n/2 and n/2 + 1
Here,
n/2 = 226/2 = 113th term
n/2 + 1 = 113 + 1 = 114th term
nth term = a+(n-1)d
113th term = 50+(112×2) = 50+224 = 274
114th term = 274 + 2 = 276
Therefore the terms are 274 and 276
