Answer 1

hope it is helpful for you

Answer 2

First number between 200 and 500 which is divisible by 8 is 208

Last number which is divisible by 8 between 200 and 500 is 496,

Now,

a(n) = a(1) + (n-1)d

496 = 208+(n-1)8

496-208 = (n-1)8

288 =(n-1)8

288/8 = n-1

36 = n-1

36+1 =n

37 =>n

It means, there are 37 numbers which are divisible by 8 between 200 and 500
