Answer:
101
Step-by-step explanation:
Given
The number of numbers lying between 81 and 1792 which are divisible by 17 is
This is in A.P
Let a be first term, d be common difference
a = 85, d = 102 – 85 = 17 and a n = 1785
using formula we get
a n = a + (n -1)d
1785 = 85 + (n – 1) 17
1785 = 85 + 17 n – 17
1785 = 68 + 17n
17 n = 1785 – 68
17 n = 1717
n = 101
So natural numbers lying between 81 and 1792 are divisible by 17 are 101.

Answer:
Your answer is 101.............
Step-by-step explanation:
Last no. divisible by 17 (in the range) is 1785
First no. divisible by 17 (in the range) is 85.
=> a= 85 , d= 17 , L=1785 , n=?
L = a+(n-1)d
=> 1785 = 85 + ( n - 1 ) 17
=> 1700/17 = n-1
=> n= 17
