Question

how many multiplies of 4 lie between 10 and 250??

Answer 1

multiples of 4 lying between 10 and 250 are
12,16,20.....248
here 16-12=20-16=4 constant
so, it forms an AP whose common difference is 4

first term,a=12

let it contains n terms
so, Tn= 248
a+ (n-1)×d=248
12+(n-1)×4=248
12+4n-4=248
4n= 248-8
n= 240/4
n=60

so, there are 60 multiples of 4 lying between 10 and 250.

Hope it is useful
