Question

How many three-digit numbers are divisible by 6 ( use nth term formula from Arithmetic Progressions)​

Answer 1

Step-by-step explanation:

Let, a= 102

d= 6

l= 996

So, we know that

l= a +(n-1) d

996= 102+(n-1)6

996= 102+6n-6

996= 96+6n

996-96= 6n

900/6=n

150 = n

Therefore, No. of three digits numbers divisible by 6 =150
