Question

Determine o 5° termo da PG (1,5)

Answer 1

$> \: resolucao \\ \\ \geqslant \: progressao \: geometrica \\ \\ q = \frac{a2}{a1} = \frac{5}{1} = 5 \\ \\ = = = = = = = = = = = \\ \\ > o \: 5 \: termo \: da \: pg \\ \\ an = a1 \times q {}^{n - 1} \\ an = 1 \times 5 {}^{5 - 1} \\ an = 1 \times 5 {}^{4}$

$an = 1 \times 625 \\ an = 625 \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant$
