A Correct answer
Explanation

The pattern follows the rule: next term = (previous term * 2) - 1.4. For example, 18 * 2 - 1.4 = 34.6, and 34.6 * 2 - 1.4 = 67.8.

AI explanation

The pattern adds an increasing decimal sequence to each term, with differences of 16.6, 33.2, 66.4 and 132.8 where each difference doubles. Adding 33.2 to 34.6 results in the missing value of 67.8.
