Question

escreva o termo Geral de cada sequência

d) (21,25,29,33,37,...)
e) (√2,2√3,3√2,4√2,....)
f) (1/3,2/3,1,4/3,5/3,2,....)
g) (38,35,32,29,26....)
h) (90,80,70,60,50,....)
i) (26,31,36,41.....)

Answer 1

d) (21,25,29,33,37,...)

An = 21+ 4(n-1)  n ∈ N

e) (√2,2√2,3√2,4√2,....) 

An = V2 + V2 .(n-1)  n ∈ N

f) (1/3,2/3,1,4/3,5/3,2,....)
 
R = 2 - 1 =  1
       3  3     3

An = 1/3 + 1/3 .(n-1)  n ∈ N

g) (38,35,32,29,26....)

An = 38 - 3(n-1)  n ∈ N

h) (90,80,70,60,50,....)

An = 90 - 10(n-1)  n ∈ N

i) (26,31,36,41.....)

An = 26 + 5.(n-1)  n ∈ N
