Solution

Claro, aquí tienes la solución paso a paso para cada una de las relaciones de recurrencia y condiciones iniciales dadas:

a) an=6an1,a0=2 a_n = 6a_{n-1}, \, a_0 = 2

Para encontrar los primeros cinco términos de la secuencia:

  • a0=2 a_0 = 2
  • a1=6a0=62=12 a_1 = 6a_0 = 6 \cdot 2 = 12
  • a2=6a1=612=72 a_2 = 6a_1 = 6 \cdot 12 = 72
  • a3=6a2=672=432 a_3 = 6a_2 = 6 \cdot 72 = 432
  • a4=6a3=6432=2592 a_4 = 6a_3 = 6 \cdot 432 = 2592

Entonces, los primeros cinco términos son: 2,12,72,432,2592 2, 12, 72, 432, 2592 .

b) an=2an1,a1=1 a_n = 2a_{n-1}, \, a_1 = 1

Para encontrar los primeros cinco términos de la secuencia:

  • a1=1 a_1 = 1
  • a2=2a1=21=2 a_2 = 2a_1 = 2 \cdot 1 = 2
  • a3=2a2=22=4 a_3 = 2a_2 = 2 \cdot 2 = 4
  • a4=2a3=24=8 a_4 = 2a_3 = 2 \cdot 4 = 8
  • a5=2a4=28=16 a_5 = 2a_4 = 2 \cdot 8 = 16

Entonces, los primeros cinco términos son: ( 1,
