Question
Hi Michael,
i'm sorry but i just didn't get the way you work out the sequence i gave you. Is there any simper ways to work out the rule?
thankyou natalie.
ps: sorry :)
Hello again, Natalie
Good you asked. I will try to make it clear now.
The rule governing this sequence is addition.
What I mean is you have to add some number to find the next one.
Try to figure out how the sequence proceeds,
There are exactly six numbers.
The difference between the first two numbers is12 isn’t it?
The difference between the second and the third is 20
The difference between the third and the fourth is 28
The difference between the fourth and the fifth is 36
The difference between the fifth and the sixth is 44. (Just subtract the numbers)
Now look at the behavior of the differences
20 is 12 + 8
28 is 20 + 8
36 is 28 + 8
44 is 36 + 8
The rule is that you have to increase the difference by 8 each time you progress. The first difference is 12; you have to add 8 each time.

Experience
I love mathematics as it is the mother of all sciences. I had an outstanding math results while I was in school. The tradition continues while I am in university. I have been helping elementary school Students for the past five years with mathematics problems. In fact, I have a brother who is four years younger than me I usually help him to understand what the crux of the question is before trying to solve it. He loves math very much, he is indeed one of the top scorers form his class in Mathematics. I didn’t stop helping my younger relatives after I joined the Engineering campus and I am more than ready to help anyone with my skill.
Education/Credentials
have a high school diploma with a 3.97 GPA; I also have many merit certificates granted for my outstanding results in high school math. I won a merit certificate for my participation in the Black Month Essay Contest. I took two different National Examinations in 2006 and 2007. In the former Exam I got 9As which includes Mathematics. I also have a score of 90 out of hundred in the later Examination which is the toughest known in Ethiopia. So you don’t have to worry about my ability to help my clients.
Past/Present Clients
I have never had an online client but I was helping students coming to me for assistance in Mathematics.
