Answer:
Smallest divisible no. (by 8) in given range \[=208\] Last divisible no. (by 8) in range \[=496\] So, \[a=208,\,\,d=8,\,\,n=?,\,\,{{a}_{n}}=496\] \[{{a}_{n}}=a+(n-1)d\] \[=208+(n-1)8=496\] \[\Rightarrow \] \[8n+208-8=496\] or \[8n=496-200=296\] \[n=\frac{296}{8}=37\] So number of terms between 200 and 500 divisible by 8 are 37.
