Transcribed Image Text:**Lesson 29: Sequence Analysis**
**Question 6/26**
Which is the correct formula for the sequence 5, 5.5, 6, 6.5,...?
- **A** \( a_n = 5(n - 1)(0.5) \)
- **B** \( a_n = 5(0.5)^{(n - 1)} \)
- **C** \( a_n = 5 + (n - 1)(0.5) \)
- **D** \( a_n = 0.5 + (n - 1)(5) \)
Determine the formula that accurately represents the given sequence based on its pattern.

#### Question 6
Which is the correct formula for the sequence 5, 5.5, 6, 6.5,...?
**Options:**
A. \( a_n = 5(n-1)(0.5) \)
B. \( a_n = 5(0.5)^{n-1} \)
C. \( a_n = 5 + (n-1)(0.5) \)
D. \( a_n = 0.5 + (n-1)(5) \)
#### Solution
To find the correct formula, observe the pattern in the sequence. The sequence starts at 5 and each term increases by 0.5. Therefore, the formula should reflect an arithmetic sequence with a common difference of 0.5.
Examine each option to see which represents this pattern.
