1.	How many natural numbers are there between 1 to 1000 divisible by 5
Answer» a=5,d=5,an=1000We have to use the formula an=a+(n-1)d1000=5+(n-1)51000-5=(n-1)5995=(n-1)5995/5=n-1199=n-1199+1=nn=200 Step - by - step explanation :a =5, d =5, tn =995995 = 5 + (n-1) × 5995 = 5 + 5n - 5995 = 5 nn = 995 ÷ 5 = 199 200
