ciao Luigi,

un piccolo rinfresco :

quanto è lunga una retta ?
da quanti punti è formata ?
quanti punti includono 2 punti in un segmento di 4 punti ?

grazie per averci aiutati !

ciao Luigi, grazie per il chiarimento,

Let's see if Tony like the translation:

En volant devant la fenêtre, il a répondu à la question de la femme "Comment ça va?" : "Jusqu'ici, tout va bien".[/COLOR][/QUOTE]

bando alle ciance ?!
 
[QUOTE=10metreh;181221]Because he posts nonsensical posts all over the place. I managed to survive by severely reducing the number of useless posts I posted. cmd didn't, and he has got banned twice and unbanned twice. I think he's OK as long as he keeps to his own mad threads. Not in the aliquot forum and most other places.[/QUOTE]


... only numbers please, thanks

This one is easy. Continuing the pattern:

[SPOILER]25600 + 3100
28900 + 3300
32400 + 3500
36100 + 3700
40000 + 3900

The pattern is (100 * n)^2 + (100 + 200x)
where n = 0, 1, 1.1, 1.2, 1.3, 1.4, 1.5....... and x = 0, 1, 2, 3, 4, 5, 6..... etc [/SPOILER]

kar_bon 2009-07-21 00:28

it's more easier:

every line is: (10*n)^2 + 100*(2n+1) for n=0,1,2,...

same as: 100n^2 + 200n + 100 -> 100*(n^2 + 2n + 1)

so every line is the sum with the value of 100*(n + 1)^2 for n=0,1,2,...

You're right. I have a tendency to make problems harder than they are.
