The number of non-square numbers lie between 500 square and 501 square is 1000
Given :
The number 500 square and 501 square
To find :
The number of non-square numbers lie between 500 square and 501 square
Concept :
If in an arithmetic progression
First term = a
Common difference = d
Then nth term of the AP
= a + ( n - 1 )d
Solution :
Step 1 of 2 :
Here the given numbers are 500² and 501²
500² = 250000
501² = 251001
The natural numbers lie between 500 square and 501 square are 250001 , 250002 , 250003 , ... , 251000
This is an arithmetic progression
Step 2 of 2 :
Find the number of term
The numbers are 250001 , 250002 , 250003 , ... , 251000
First term = a = 250001
Common Difference
= d
= 250002 - 250001
= 1
Let 251000 is the nth term of the AP
⇒ a + ( n - 1 )d = 251000
⇒ 250001 + ( n - 1 ) = 399
⇒ n + 250000 = 251000
⇒ n = 251000 - 250000
⇒ n = 1000
The number of non-square numbers lie between 500 square and 501 square is 1000
