Question

How many multiple of 4 lies between 10 and 250​

Answer 1

let it be a AP

8,12,16,..........248

a=8

d=4

an=248

n=?

an=a+(n-1)d

248=8+4n-4

248=4+4n

248-4=4n

244=4n

$n = \frac{244}{4}$

$n = 61$

so,there are total 61 numbers between 4 and 250 which are divisible by 4.

Answer 2

Answer:

hey mate here is your answer.....

Step-by-step explanation:

➡️ Some of multiple of 4 between 10 and 250 is 12,16,20,24 ........

➡️ So the first term will be 12 and common difference as 4

➡️ When we divide 250 by 4 the remainder will be 2, therefore 250-2 = 248 which is divisible by 4

➡️ The series will be 12,16,20,24......248

☑️ Let 248 be the nth term of this A.P

▶️ a = 12 , d = 4 , an = 248

☑️ an = a + ( n - 1 ) d

➡️ 248 = 12 + ( n - 1 ) x 4

➡️ 236 / 4 = n - 1

➡️ 59 = n - 1

➡️ n = 60

☑️ Therefore there are 60 multiples of 4 between 10 and 250.

Hope it helps!☺️

Have a nice day...
