Question

How many multiples of four is between 10 and 250

Answer 1

First term in this series will be 12. also the last digit will be 248.

the the series will be 12,16,20……….248.

it is a arithmetic series with first term a=12 and common difference of 4.

with last term as 248.

so 248=12+(n-1)x4 (lets assume it has n such numbers.)

(n-1).4= 248–12=236

n-1=236/4=59

n=59+1=60.

so 60 multiples of 4 lie between 10 and 250.

Answer 2

Heya!!!


Here's ur answer..

_____________

First term = 12

Last term = 248

Common difference = 4

L = a + (n-1) d
248 = 12 + (n-1) 4
236 = (n-1) 4
n-1 = 236/4
n-1 = 59
n = 60


So, there are 60 multiples of 4 between 10 & 250.
