Find the next term in the following alphanumeric series:

C12W, D20O, G30I, L42E, ?

Looking at the series: C12W, D20O, G30I, L42E, ?

Each term consists of three parts: First letter, Number, Last letter

---

Analyzing the first letters: C, D, G, L, ?

Position in alphabet:

• C = 3rd letter
• D = 4th letter
• G = 7th letter
• L = 12th letter

Differences between positions:

• 4 - 3 = 1
• 7 - 4 = 3
• 12 - 7 = 5

The differences form the pattern: 1, 3, 5 (consecutive odd numbers)

Next difference = 7

Position of next letter = 12 + 7 = 19

19th letter = S

---

Analyzing the numbers: 12, 20, 30, 42, ?

Differences:

• 20 - 12 = 8
• 30 - 20 = 10
• 42 - 30 = 12

The differences form the pattern: 8, 10, 12 (increasing by 2)

Next difference = 14

Next number = 42 + 14 = 56

---

Analyzing the last letters: W, O, I, E, ?

Position in alphabet:

• W = 23rd letter
• O = 15th letter
• I = 9th letter
• E = 5th letter

Differences between positions:

• 15 - 23 = -8
• 9 - 15 = -6
• 5 - 9 = -4

The differences form the pattern: -8, -6, -4 (increasing by 2)

Next difference = -2

Position of next letter = 5 + (-2) = 3

3rd letter = C

---

The next term is S56C.

Therefore, the answer is Option 2: S56C.
