D Correct answer
Explanation

The pattern is multiplication by -2: 0.05 * -2 = -0.1, -0.1 * -2 = 0.2, 0.2 * -2 = -0.4, -0.4 * -2 = 0.8.

AI explanation

The numbers in this series are multiplied by -2 to get the next term. So, -0.1 multiplied by -2 gives 0.2. Checking this with the next term, 0.2 multiplied by -2 equals -0.4, which confirms 0.2 is the missing number.
