To solve this problem, we need to understand that the mean (or average) of a set of numbers is the sum of the numbers divided by the count of numbers.

1. The mean of the first 3 terms is 14. Therefore, the sum of the first 3 terms is 14 * 3 = 42.

2. The mean of the next 2 terms is 18. Therefore, the sum of the next 2 terms is 18 * 2 = 36.

3. The total sum of all 5 numbers is 42 (from the first 3 terms) + 36 (from the next 2 terms) = 78.

4. The mean of all 5 numbers is the total sum divided by the count of numbers, which is 78 / 5 = 15.6.

So, the answer is (d) 15.6.
