Question

Qual são os múltiplos de 5entre 8e523

Answer 1

Olá Bih Almeida!

Temos um exercício de P.A

a1=10

n=?

r=5

an=520

an=a1+(n-1).r

520=10+(n-1).5

520=10+5n-5

520-10+5=5n

515=5n

n=515/5

n=103

Portanto existem 103 múltiplos de 5 entre 8 e 523.

10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100,105,110,115,

120,125,130,135,140,145,150,155,160,165,170,175,180,185,190,195, 200, 205,

210,215,220,225,230,235,240,245,250,255,260,265,270,275,280,285,

290,295,300,305,310,315,320,325,330,335,340,345,350,355,360,365,
