Question

2) Interpolar 6 meios aritméticos entre 1 e 22.

Answer 1

$> \: resolucao \\ \\ \geqslant \: progressao \: \: aritmetica \\ \\ an = a1 + (n - 1)r \\ 22 = 1 + (8 - 1)r \\ 22 = 1 + 7r \\ 22 - 1 = 7r \\ 21 = 7r \\ r = \frac{21}{7} \\ r = 3 \\ \\ \\ pa > \: (1.4.7.10.13.16.19.22.... \: ) \\ \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \geqslant \geqslant \geqslant$

Answer 2

Explicação passo-a-passo:

$r = \frac{an - a1}{m + 1}$

$r = \frac{22 - 1}{6 + 1 } = \frac{21}{7} = 3$

PA= 1, 4, 7, 10, 13, 16, 19, 22
