Answer : 1. "28 "
Explanation :

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, an = 196,

d = 7, n = 8

a= a + (n –1)d

⇒196 = 7 + (n – 1) × 7

⇒ 

⇒ n = 27 + 1 = 28

Note : We can find the answer after dividing 200 by 7. The quotient is our answer.
