Find the next term (?) in the following alpha-numeric series:

A-01, D-04, G-09, J-16, M-25, ?

P-36

The correct answer is Option (3) → P-36

To find the next term in the series, we can analyze the alphabetical and numerical parts separately.

1. The Alphabetical Sequence

Look at the positions of the letters in the English alphabet:

• A is the 1st letter.
• D is the 4th letter. (1 + 3)
• G is the 7th letter. (4 + 3)
• J is the 10th letter. (7 + 3)
• M is the 13th letter. (10 + 3)

Following this pattern, the next letter should be the 16th letter ($13 + 3$):

• The 16th letter is P.

2. The Numerical Sequence

Look at the numbers following the letters:

• 01 = $1^2$
• 04 = $2^2$
• 09 = $3^2$
• 16 = $4^2$
• 25 = $5^2$

The numbers are the squares of consecutive integers. The next number in the sequence should be the square of 6:

• $6^2$ = 36.

Conclusion

Combining the two parts, the next term in the series is P-36.
