Question

Escreva os múltiplos de 8 maiores que 130 e menores que 170: me ajudaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer 1

múltiplos de 8:

136: 8 = 17

168: 8 = 21

a1 = 136

an = 168

r = 8

an = a1 + (n -1).r

168 = 136 + (n - 1).8

168 - 136 = 8n - 8

32 = 8n - 8

32 + 8 = 8n

40 = 8n

40/8 = n

5 = n

n = 5

(136, 144, 152, 160, 168)

espero ter ajudado, bons estudos
