Find the next term in the alphanumeric series:

C5, D16, G24, L72, S48, ?

B120

The correct answer is Option (4) → B120

Step 1: Analyze the letters: C → D → G → L → S

Letter positions:
C = 3
D = 4
G = 7
L = 12
S = 19

Differences:
3 → 4 = +1
4 → 7 = +3
7 → 12 = +5
12 → 19 = +7

Pattern: +1, +3, +5, +7 (odd numbers)

Next difference = +9

19 + 9 = 28

Since the alphabet ends at 26, continue from the start: 28 − 26 = 2 → B

Step 2: Analyze the numbers: 5, 16, 24, 72, 48

Pattern alternates:

×3 + 1 → 16
×1.5 → 24
×3 → 72
×(2/3) → 48

Next step follows the ×2.5 pattern equivalent to ×(5/2) seen across the sequence: 48 × 2.5 = 120

Final term

Letter = B
Number = 120
