## Exercise 15

### Question

export const metadata = {
  title: "Number Sequence",
  authors: [{ name: "Nabil Akbarazzima Fatih" }],
  date: "12/27/2025",
};

<InlineMath math="4, 5, 8, 2, \dots, \dots, 32, -4, 64, -7" />

The correct values to complete the number sequence are...


### Choices

- [ ] $$12, -1$$
- [x] $$16, -1$$
- [ ] $$-2, 12$$
- [ ] $$12, 16$$
- [ ] $$-1, -2$$

### Answer & Explanation

export const metadata = {
  title: "Number Sequence",
  authors: [{ name: "Nabil Akbarazzima Fatih" }],
  date: "12/27/2025",
};

This sequence consists of two alternating patterns.

First pattern (odd positions):

<MathContainer>
  <BlockMath math="4 \xrightarrow{\times 2} 8 \xrightarrow{\times 2} \mathbf{16} \xrightarrow{\times 2} 32 \xrightarrow{\times 2} 64" />
</MathContainer>

Second pattern (even positions):

<MathContainer>
  <BlockMath math="5 \xrightarrow{-3} 2 \xrightarrow{-3} \mathbf{-1} \xrightarrow{-3} -4 \xrightarrow{-3} -7" />
</MathContainer>

The missing terms are the <InlineMath math="5" />th term (from the first pattern) and the <InlineMath math="6" />th term (from the second pattern).

For the <InlineMath math="5" />th term:

<MathContainer>
  <BlockMath math="8 \times 2 = 16" />
</MathContainer>

For the <InlineMath math="6" />th term:

<MathContainer>
  <BlockMath math="2 - 3 = -1" />
</MathContainer>

Therefore, the correct values to complete the sequence are <InlineMath math="16" /> and <InlineMath math="-1" />.
