The output is n + 5
Explanation:
From the table:
when input = 2
output = 7
output = input + difference
7 = 2 + difference
difference in output and input = 7 - 2 = 5
when input = 6
output = 11
output = input + 5
11 = 6 + 5
when input = 7
output = 12
output = input + 5
12 = 7 + 5
when input = n
output = ?
output = input + difference
difference = 5
output = n + 5
The output is n + 5
