Answer 2

Answer:

150

Step-by-step explanation:

first 3 digit number divisible by 6 = 102

last 3 digit number divisible by 6= 996

aₙ = a+(n-1)d,

aₙ - last term=996

a= first term=102

d= common difference=6

996=102+(n-1)6

894=(n-1)6

894=6n-6

900=6n

n=900/6=150

so the number of 3 digit numbers divisible by 6 =150
