Sequences and Functions


In math we are learning about sequences and functions.  For example:
 
Input, x
1
2
3
4
x
Output,  y  
5
6
7
8
x + 4

When the input is 1, the output is 5.
 
After examining the pattern we can see that the output is always 4 more than the input.
 
Therefore:    output = input + 4      or      y = x + 4
 
What would the output be if the input was 12?
