Question

find the all natural numbers from 1 to 200 which are divisible by 7 ​

Answer 1

Answer:

28

Explanation:

The last number in 1 to 200 divisible by 7 is 196.

Now take a=7 , d=7 and l=196

So, using A.P. formula we get,

196 = 7 + (n-1)7

189 = 7(n-1)

27 = n-1

n = 28

Therefore there are 28 natural numbers between 1 to 200 which are divisible by 7.
