Question

URGENTEE! PORFAVOR!
Determine as sequências numéricas a seguir:
a) an = 3n, n ∈ Z
b) an = n² - 2, n ∈ N*
c) an = 2n + 1, n ∈ Z
d) an = 2n² + 2, n ∈ N
e) an = n - 1, n ∈ Z

Answer 1

Resposta:

a) an = 3n

(3,6,9,12,15....)

b) an = n² - 2

(-1,2,7,14....)

c) an = 2n + 1

(3,5,7,....)

d) an = 2n² + 2

(4, 10,20....)

e) an = n - 1

(0,1,2....)
