✧*:.｡. Answer .｡.:*✧

• Three digit natural numbers divisible by 5 are :
• 100 , 105 , 110 , ..........., 995.

• Here, a = 100 , d = (105-100=5) , tn = 995

• tn = a + (n-1)d {formula}
• ↝ 995 = 100 + (n-1)×5
• ↝ 995 = 100 + 5n -5
• ↝ 995 = 95 +5n
• ↝ 5n = 995-95
• ↝ 5n = 900
• ↝ n= 900/ 5
• ↝ n= 180
