Here is the completed table:

The differences are not constant, but they increase by 2 for each successive difference.

<< back to Problem D1


 

Problem D2

Here is the completed table:

2nd differences

The difference between outputs forms a linear function, and the second differences are constant (in this case, they're always equal to 2).

<< back to Problem D2


 

Problem D3

Here is the completed table:

2nd differences

As before, the first differences form a linear function, and the second differences will always be constant.

<< back to Problem D3
