Complete the Decimal Sequence: Finding Missing Terms in 0.9, 0.6, ?, ?

Complete the following sequence:

$0.9,0.6,?,\text{?}$

To solve this problem, we'll follow these steps:

• Step 1: Identify the sequence pattern.
• Step 2: Calculate the differences between known terms.
• Step 3: Use the difference to find missing terms.
• Step 4: Validate against the given choices.

Now, let's work through each step:
Step 1: Identify the sequence pattern from the given terms $0.9$ and $0.6$.
Step 2: Calculate the difference between $0.9$ and $0.6$, which is $0.9 - 0.6 = 0.3$. This indicates the sequence decreases by $0.3$ with each term.
Step 3: Apply this difference to find the next terms:
- Subtract $0.3$ from $0.6$: $0.6 - 0.3 = 0.3$
- Subtract $0.3$ from $0.3$: $0.3 - 0.3 = 0$
Step 4: Validate against the given choices; the only choice that matches this sequence is $0.3, 0$.

Therefore, the solution to the problem is $0.3, 0$.
