Question

how many multiple of 4 lie between 10 and 250?

Answer 1

there are 60 multiple of 4 lie between 10 and 250

Answer 2

Answer:-

Multiples of 4 lie between 10 and 250: 12,16,20,....248

Let the total number of multiples of 4 lie between 10 and 250 be n.

$\large\sf{Here,}$

$\small\sf{a=12}$

$\small\sf{d=16-12=4}$

$\large\sf{Given\:that:}$

$\small\sf{an=a+(n-1)d=248}$

$\small\sf{12+(n-1)(4)=248}$

$\small\sf{4(n-1)=236}$

$\small\sf{n-1=\frac{236}{4}=59}$

$\small\sf{n=60}$

Hence, the total number of multiples of 4 oie between 10 and 250 is 60.
