Step-by-step explanation:
The integers between 200 & 500 which are divisible by 8 are: 208, 216,224…496.
This is an AP, the first term is 208 and the last term is 496.
Last term is L=a+(n-1)dL=a+(n−1)d
where, n is the number of terms , a is the first term and d is the common difference.
a=208 , d=8 , L=496
496=208+(n-1)8496=208+(n−1)8
288=(n-1)8288=(n−1)8
n-1=36n−1=36
n=37n=37
