Question

Below is the table of values of a function. Write the output when the input is

n


input 1 4 9 n

output 5 8 13 ?

What is the last output ?

Answer 1

n + 4

Or 20

Explanation:

Depends on how you see it the answer could be n´+4 since that´s how the function is working, and almost all of the time the independent clauses are actually independent and do not follow any progression.

But if there is a progression in the input, we can see that they are adding up uneven numbers to the input, so first we added 3, then we added 5, and last we should add 7: so the input would be 7+9= 16, the input in the forth spot should be 17, and the output should be 20.

Answer 2

The function is arithmetic where output = input +4


Input: 1 4 9 9 + 7
Output: 1+4 4+4 9+4 9+7+4
Output: 5 8 13 20

Last output is 20
