Question

Imi explica si mie cineva cum se face exercitiul E2 ? Subpunctele c) si d) va rog!

Answer 1

c) x n = n / n+2 * X n-1
x2 = 2/4 * x1 
x1=4
x2 = 2/4 * 4 = 8/4 = 2 , asa si la x3 , x4

Answer 2

Pai simplu:

C)X2=2/4*4 = 2 ;X3=3/5  * 2=6/5; X4=4/6 * 6/5 = 24/30=12/15

   Xn+2=n+2/n+4*Xn+1;

D)X2=rad(rad(2)+2); X3=rad(rad(rad(2)+2);X4=rad(rad(rad(rad(2)+2);
