Find the next term in the alphanumeric series:

C5, D16, G24, L72, S48, ?

Looking at the letter pattern:

C, D, G, L, S, ?

The position of each letter in the alphabet:

• C = 3rd letter
• D = 4th letter
• G = 7th letter
• L = 12th letter
• S = 19th letter

The differences between positions:

• 4 - 3 = 1
• 7 - 4 = 3
• 12 - 7 = 5
• 19 - 12 = 7

The differences form the sequence 1, 3, 5, 7 (consecutive odd numbers).

The next difference should be 9.

$19 + 9 = 28$

Since there are only 26 letters in the alphabet:

$28 - 26 = 2$

The 2nd letter is B.

Looking at the number pattern:

5, 16, 24, 72, 48, ?

Examining the ratios between consecutive terms:

• $\dfrac{16}{5} = 3.2 = \dfrac{16}{5}$
• $\dfrac{24}{16} = 1.5 = \dfrac{3}{2}$
• $\dfrac{72}{24} = 3$
• $\dfrac{48}{72} = \dfrac{2}{3}$

The pattern of multipliers alternates between increasing and decreasing values.

Following the pattern:

$48 \times 2.5 = 120$

---

The next term combines:

• Letter: B
• Number: 120

Therefore, the answer is B120.
