(D) The given series is $1, 3, 6, 10, 15, ?$.Observe the differences between consecutive terms:$3 - 1 = 2$$6 - 3 = 3$$10 - 6 = 4$$15 - 10 = 5$The differences are increasing by $1$ each time $(2, 3, 4, 5, ...)$.Following this pattern,the next difference should be $6$.Therefore,the next term is $15 + 6 = 21$.
