Talking A little complex problem I would like you guys to solve, and to help me as well :)

Hello i'm new to the forum , and i have been recently trying to find a formula for some numbers, but with no success.

example:
Quote:
value 3 = 11
value 5 = ?
value 6 = ?

value 7 = 34
value 10 = ?
value 11 = ?
value 12 = 88
value 13 = ?
value 14 = 137
value 15 = ?
value 16 = 176
value 17 = ?
value 18 = 220
value 19 = ?
value 20 = 269
value 22 = ?
value 23 = 411
value 24 = ?
value 25 = 530
value 27 = ?
value 28 = 750
value 29 = ?
value 30 = 926
value 32 = ?
value 33 = 1240
value 34 = ?
value 35 = 1561
another...

Quote:
each value is calculated by its number divided by 2 so in this case value 3 = 11 so 5,5 + 5,5

value 12 (88;2x44) + value 14 (137;2x68,5) = 112,5 but the required value is 122 which makes a difference of 9,5
BUT
value 14 + value 12 for a value of 103 which is the same difference 9,5
another example:

Quote:
value 3 (11/2x5,5) + value 7 (34/2x17) = 22,5 should make 27 so a difference of 4,5
same goes the other way around
value 7 + value 3 should make 18 so also a difference of 4,5
and yet another more complex example

Quote:
value 33 (1240;2x620)+4 + value 35 (1561;2x780,5)+4 = 1408,5
what should the difference be? and what is the required number?
If this is too hard to solve or you can't find the solution then there's no problem, all i want is for everyone to help

One last thing, if you can find all the formulas and calculations please post them, all i want to know is HOW to reach the solution

Which exercise is your poll referring to? Or does it refer to all.

By the way, if you can't solve it, there's no biggy, it's just some thing i wanted to "try" to know about, but i don't really see if this thing really has a formula :P
But if anyone can solve, i give you my greatest honors

Extracting data

I want to know how I can find out what the number of attendees are based on the last 11 months and extrapolate this from an annual data sheet showing the last 12 months for example ; a total of 600 people attended courses
200 went onto employment
200 volunteered
200 did nothing
The data I have is for 12 months I would like to know what this would be over 11 months please Anyone know?

it would be wise to start a new problem with a new thread ...
