How many natural numbers divisible by 7 are there between 3 and 200?

[A]27

[B]28

[C]29

[D]36

**28**

Number just greater than 3 which is divisible by 7 = 7

Number just smaller than 200 which is divisible by 7 = 196

Here, a = 7, a_{n} = 196, d = 7, n = 8

∴ a_{n} = a + (n – 1)d

=> 196 = 7 + (n – 1) 7

=> n = 27 + 1 = 28

Hence option [B] is right answer.
