Question

Calcule o décimo termo da p.g 2,4

Answer 1

Explicação passo a passo:

Na PG temos

a1 = 2

a2 = 4

q = a2/a1 = 4/2 = 2>>>>

an = a1 * q^n-1

a10 = 2 * 2^9

a10 = 2 * 512 = 1024 >>>>resposta

Answer 2

$> \: resolucao \\ \\ \geqslant \: progressao \: \: geometrica \\ \\ q = \frac{a2}{a1} = \frac{4}{2} = 2 \\ \\ = = = = = = = = = = = =$

$> \: o \: 10 \: termo \: da \: pg \\ \\ an = a1 \times q {}^{n - 1} \\ an = 2 \times 2 {}^{10 - 1} \\ an = 2 \times 2 {}^{9} \\ an = 2 \times 512 \\ an = 1024 \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant$
