Question

b) como se chama o termo 9? o ?​

Answer 1

Resposta:

An= A₁ + (n-1) * r

An= A₁ + (n-1) * r149= 9 + (n-1) * 4

An= A₁ + (n-1) * r149= 9 + (n-1) * 4149= 9 + 4n-4

An= A₁ + (n-1) * r149= 9 + (n-1) * 4149= 9 + 4n-4149-9+4= 4 n

An= A₁ + (n-1) * r149= 9 + (n-1) * 4149= 9 + 4n-4149-9+4= 4 n144= 4n

An= A₁ + (n-1) * r149= 9 + (n-1) * 4149= 9 + 4n-4149-9+4= 4 n144= 4nn=36 termos
