Question

Identifique o próximo numero da sequencia 1,1,2,-1

Answer 1

Given : sequence: 1, 1, 2, -1,  

To Find : next number in the sequence

Solution:

1, 1, 2, -1,  

​ 1  + 1  = 2

1  -  2 = - 1

2 + (-1) = 1

 

 Next number in sequence is 1

logic is

Tₙ₊₂ = Tₙ + (-1)ⁿ⁺¹Tₙ₊₁     where T₁ = 1   T₂ = 1

n = 1 , T₃ = T₁  + (-1)¹⁺¹T₂  = 1  + 1 =  2

n = 2  T₄ = T₂  + (-1)²⁺¹T₃  = 1  - 2 =  -1

n =3  T₅ = T₃  + (-1)³⁺¹T₄  = 2  + (-1) = 1
