Median= 26
n=12
Median=(n/2)th term + (n+1/2)th term/2
Median = (12/2)th + (12+1/2) / 2
Median= 6th + 7th/2
26 = x+4 +30/2
26 = x+34/2
x+34 = 26 × 2
x+34 = 52
x = 52 - 34
x = 18
Median= 26
n=12
Median=(n/2)th term + (n+1/2)th term/2
Median = (12/2)th + (12+1/2) / 2
Median= 6th + 7th/2
26 = x+4 +30/2
26 = x+34/2
x+34 = 26 × 2
x+34 = 52
x = 52 - 34
x = 18
