Progression: 11, 18, 25

Rule: Add 7

Step-by-step explanation:

Given

List of numbers: 8, 11, 13, 18, 25, 37

Sample Progression: 8, 13, 18; with common difference of 5

Required

Form a different progression using any three listed numbers

To solve this; we'll make use of trial and error methods;

NB: I've tried several numbers; So, I'll just stick to the one that works

To start with;

Select - >11

Add 7 to 11: 11 + 7 - > 18

Add 7 to 18: 18 + 7 - > 25

With the above illustration, we've successfully used three numbers (11, 18 and 25) to form a new progression and the rule is to add 7
