Question

Determine o valor de n da equação P(n+2)=8P(n+1)

Answer 1

P(n+2)=8P(n+1)

(n+2)! = 8.(n+1)!

(n+2).(n+1)! = 8.(n+1)!

(n+2) = 8.(n+1)!/(n+1)!

n+2 = 8

n= 8 -2

n= 6 ✓

Answer 2

Resposta:

Explicação passo-a-passo:

P(n+2)=8P(n+1)

Pn+2p=8Pn+8p

-8pn+pn=8p-2p

-7pn=6p

Pn=-6/7p

n=-6/7
