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
an = 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.
