Question

determine quantos multiplos de 6 ha entre 100 e 1000

Answer 1

1000/6=166,66==>166*6=996 

a1=102 
r=6 
an=996 

an=a1+(n-1)r 

996=102+(n-1)6 

996-102+6=6n 

n≈150

Answer 2

100/6=16,66==>17*=102 1000/6=166,66==>166*6=996 a1=102 r=6 an=996 an=a1+(n-1)r 996=102+(n-1)6 996-102+6=6n n=150
