The first term in a sequence is 12

The term-to-term rule is + 4

What is the 5th term?

The first term of the sequence is \(12\), and each term is obtained by adding 4 to the previous term. 

We can calculate the first few terms as follows:

- 1st term: \(12\)  
- 2nd term: \(12 + 4 = 16\)  
- 3rd term: \(16 + 4 = 20\)  
- 4th term: \(20 + 4 = 24\)  
- 5th term: \(24 + 4 = 28\)  

Thus, the 5th term is \(28\).

Here are 5 related questions to expand on this:

1. What would be the 10th term in the sequence?
2. How can you express the \(n\)-th term of this sequence algebraically?
3. What type of sequence is this, and what is its common difference?
4. Can you determine the sum of the first 5 terms of this sequence?
5. How would the sequence change if the term-to-term rule was \(+6\) instead of \(+4\)?

**Tip:** Sequences like this are called arithmetic sequences because they have a constant difference between consecutive terms.
