Question

how many how many multiples of 4 lies between 10 and 250 ​

Answer 1

Answer:

60

Step-by-step explanation:

Multiples of 4 lies between 10 and 250 are 12, 16, 20, ...., 248.

These numbers form an AP with a = 12 and d = 4.

Let number of three-digit numbers divisible by 4 be n,

an = 248

⇒ a + (n - 1) d = 248

⇒ 12 + (n - 1) × 4 = 248

⇒4(n - 1) = 248

⇒ n - 1 = 59

⇒ n = 60

Answer 2

between 10 and 250

11 12 13..........249

12 is multiple of 4

248 is multiple of 4

difference between the numbers is 4

therefore

ap is

12 16 20........248

a=12

an or last term = 248

d = 4

an = a+ (n -1)d

248=12+(n-1)4

248 - 12 = 4n - 4

236 + 4 = 4n

n = 240/4

n = 60

therefore there are 60 such numbers
