Expert Answer:
The numbers between 200 and 700 which are multiples of 11:
209, 220, ......, 693
This is an AP with first term = a = 209 and common difference = d = 11.
Let the number of terms be n.
an = a + (n - 1)d
693 = 209 + (n - 1)(11)
(n - 1)(11) = 484
n - 1 = 44
n = 45
Thus, there are 45 natural numbers between 200 and 700 which are multiples of 11.
