Answer:180
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 common difference d=5.
Let there be n terms in this sequence. Then,
an =995 ⇒ a+(n−1)d
995 = 100+(n−1)×5
⇒n−1 = 179
⇒n = 180
