To calculate the solutions to the question, we have discovered a usable and accurate method. The first step we have found to uncover the time table used in the questions to identify the difference between each number indicated, this will be the first new number of the pattern. The following step you have to complete is working out if the number is shifted up or down. What we mean by shifted, is the amount that is added or subtracted from the original multiplication number in the pattern. The final step is to write how much is added to, or how much is subtracted from it. We hope this method had assisted you in understanding the process of completing these problems.
The official formula for these problems are:
Example
A B C D E
11 20 29 38 47
If we label each number from A-E the formula would be:
b-a=9 (20-11) +2=11
b-a=9 (+11) +2=20
b-a=9 (+20) +2=29
b-a=9 (+29) +2=38
b-a=9 (+38) +2=47
