Answer 1

Answer:

180 Mark me as brainliest and give thanks! :)

Step-by-step explanation:

The smallest and the largest numbers of three digits, which are divisible by 5 are 100 and 995 respectively,  

So, the sequence of three digits numbers which are divisible by 5 is 100,105,110,...,995.  

It is an AP with first term a=100 and a common difference d=5.

Let there be n terms in this sequence. Then,

a  

n

​  

=995⇒a+(n−1)d

995=100+(n−1)×5

⇒n−1=179

⇒n=180
