There are 47 multiples of 5 between 10 to 250.
Given,
The numbers between 10 to 250.
To Find,
The multiples of 5 between 10 to 250.
Solution,
The number between 10 to 250 that are multiples of 5 form an A.P as,
15, 20,..., 245
where
a = 15
d = 5
aₙ = 245
Now, using the formula of the nth term of A.P
aₙ = a+(n-1)d
245 = 15+(n-1)5
230 = 5n-5
5n = 235
n = 47
Hence, there are 47 multiples of 5 between 10 to 250.
