Question

A partir del termino general calcula 4 terminos
a) An= n+20=
b) Bn= n2+4=
c)Cn= n/n+1=

Answer 1

Respuesta:

a) 21 , 22 , 23 , 24

b) 5 ,8 ,13 ,20

c) 1/2 , 2/3 , 3/4 , 4/5

Explicación paso a paso:

a)  a₁ = 1 + 20 = 21

   a₂ = 2 + 20 = 22

  a₃ = 3 + 20 = 23

   a₄ = 4 + 20 = 24

b ) b₁ = 1² +4 = 1 + 4 = 5

    b₂ = 2²+ 4 = 4 + 4 = 8

    b₃ = 3² + 4 = 9 + 4 = 13

    b₄ = 4² + 4 = 16 + 4 = 20

c)  c₁ = 1/1 + 1 = 1/2

    c₂ = 2/2 + 1 = 2/3

    c₃ = 3/3+1 = 3/4

    c₄ = 4/4+1 = 4/5
