Question

pentru fiecare dintre sirurile de mai jos ,observati regula de alcatuire si scrieti inca inca trei nr : a) 10,16,22,.... b) 10 ,21 ,32, ... c) 2 ,6, 18 ,..... d) 5 ,11, 23,.... e) 4 ,11, ,32,... f) 12 ,23, 34,....

Answer 1

a) Regula = +6

10,16,22,28,34,40.

10+6= 16

16+6=22

b) 10,21,32,43,54,65

Regula: +11.

c) 2,6,18,54,162,486.

Regula: x3

d) 5,11,23,47,95,191.

Regula = Fusul orar doar ca -1. Gen: 5+6=11 11+12=23(daca era 12 =24) dupa 23+24=47, 47+48=95 etc.

e)4,11,32,95,284,851

Algoritmul meu este putin ciudat, dar e logic.

4+7=11 7x3=21 21+11=32  21x3=63, 63+32=95 , 63x3=189. 189+95=284

189x3=567 567+284=851

f)12,23,34,45,56,67.

Regula = +11
