Numbers which are divisible by 7 between 200 and 400 are : 203,210,217,........,399 These numbers form an arithmetic progression with first term, $$a$$ = 203 and last term, $$l$$ = 399 Common difference, d = 7 Using, $$l = a + [(n - 1) imes d]$$ => $$399 = 203 + (n - 1) imes 7$$ => $$(n - 1) = frac{(399 - 203)}{7} = frac{196}{7} = 28$$ => $$n = 28 + 1 = 29$$ => Ans - (B)
