Question

how many integers between 200 and 400 are divisible by 8​

Answer 1

Answer:

25

Step-by-step explanation:

400= 208 + ( n-1) 8

400= 208 + 8n -8

400= 200 +8n

200/8 = n

n = 25

Answer 2

the integers between 200 and 500 which divisible by 8 are..

208 216 224 ..... 496

let..t1=a=208.

d=8

tn=496

n=?

tn= a +(n-1 )×d

496=208+(n-1)×8

496=208+8n-8

496=200+8n

8n=496-200

8n=296

n=296/8

n=37

hence,there are 37 numbers between 200 and 500 which are divisible by 8.
