(C) The given series consists of two alternating sub-series.The numbers at even positions form the series: $18, 12, ?$.The numbers at odd positions form the series: $5, 10, 15$.Analyzing the even position series: $18, 12, ?$. The difference between consecutive terms is $18 - 6 = 12$. Following this pattern,the next term should be $12 - 6 = 6$.Therefore,the missing number is $6$.
