Explicație pas cu pas:

CERINTA: SE CONSIDERA PERECHEA DE NR. NAT. (An, Bn), UNDE An=2*(N+1) ȘI Bn=3*(N-1),PENTRU N> SAU EGAL CU 2.

1) (x, 300)

b = 300 = 3(n - 1)

n - 1 = 100

n = 101

a = 2(n + 1) = 2*102 = 204

perechea este (204, 300)

__________

2) (2000, y)

a = 2000 = 2(n + 1)

n + 1 = 1000

n = 999

b = 3(n - 1) = 3*998 = 2994

perechea este (2000, 2994)
