Find the next term in this series
A1Z, E5V, I9R, ______.

Options

A. N13M
B. O12L
C. M13N
D. L12O

Answer

To find the next term in the series A1Z, E5V, I9R, we need to analyze the pattern in the given terms.

1. **Identify the first letters of each term:**
- A, E, I
- These letters are in the sequence of vowels. The pattern is that each letter is moving forward by 4 positions in the alphabet:
- A (1st letter) to E (5th letter) = 4 steps
- E (5th letter) to I (9th letter) = 4 steps

**Hint:** Look for a consistent pattern in the first letters.

2. **Determine the next letter after I:**
- Continuing the pattern, we move 4 steps ahead from I (9th letter):
- I (9) + 4 = M (13th letter)

**Hint:** Use the alphabet to count the steps forward.

3. **Identify the middle numbers of each term:**
- The middle numbers are 1, 5, 9.
- The pattern here is also increasing by 4:
- 1 to 5 = 4
- 5 to 9 = 4

**Hint:** Look for a numerical pattern in the middle numbers.

4. **Determine the next number after 9:**
- Continuing the pattern, we add 4 to 9:
- 9 + 4 = 13

**Hint:** Keep the same numerical pattern in mind.

5. **Identify the last letters of each term:**
- The last letters are Z, V, R.
- These letters are moving backward in the alphabet:
- Z (26th letter) to V (22nd letter) = -4
- V (22nd letter) to R (18th letter) = -4

**Hint:** Check the relationship between the last letters.

6. **Determine the next letter after R:**
- Continuing the pattern, we move 4 steps backward from R (18th letter):
- R (18) - 4 = N (14th letter)

**Hint:** Use the alphabet to count the steps backward.

7. **Combine the results:**
- The next term in the series is M13N.

**Final Answer:** M13N
