Question

DETERMINE O DECIMO TERMO DA P.G (1,2,4...)

Answer 1

$a_{n}$ = a₁.$q^{n-1}$           q = a₂/a₁ = 2/1 = 2
a₁₀ = 1.2¹⁰⁻¹
a₁₀ = 2⁹
a₁₀ = 512

Answer 2

Bom dia Gente

PG

u1 = 1
u2 = 2

razão
q = u2/u1 = 2/1 = 2

termo geral
un = u1*q^(n-1)

decimo termo
u10 = u1*q^(10-1)
u10 = 1*2^9 = 512
