How many integers between 197 and 303 divisible by 4?

Answer 1

An=A¹+(n-1)d

300=200+(n-1)4

300-200=4n-4

100+4=4n

¼(104=4n)

26=n

An=A¹+(n-1)d

300=200+(n-1)10

300-200=10n-10

100+10=10n

⅒(110=10n)

11=n

Find the least common multiple of (4,10)

4 8 12 20 24

10 20 30

LCM=20

Then we are going to find the numbers between 200 and 300 that are divisible by 20.

200, 220, 240, 260, 280, 300

We have 6 numbers

26+11=37-6= 31

The answer is 31
