Question

Nas sequencias a seguir indentifique o padrão de cada uma e complete as
A)3,12,21,30...
B)32,27,22,17...
C)5,16,27,38...
D(1,4,9,16,25...

Answer 1

A) 3,12,21,30,39,48,57,66,75,.....
R = A2 - A 1
R = 12 - 3
R = 9
12 - 3 = 9
21 - 12 = 9
30 - 21 = 9
30 + 9 = 39

B)32,27,22,17,12,7,2,-3,-8,-13.....
R = A 2 - A 1
R = 27 - 32
R = -5
 
 C)5,16,27,38,49,60,71,82,93,.......
R = A 2 - A 1
R = 16 - 5
R = 11

 D)1,4,9,16,25,36,49
  +3,+5,+7,+9,+11,+13
 A 1 = 1
A 2 = 4 
A 3 = 9
A 4 = 16
A 5 = 25
A 6 = 36
