Select the wrong term in the given alpha-numeric series.
D4, G8, J12, M32, P64

Correct option is D

​$$\textbf{Alphabetic positions (increasing by +3):} \\\text{D(4)} \rightarrow \text{G(7)} \rightarrow \text{J(10)} \rightarrow \text{M(13)} \rightarrow \text{P(16)} \\\text{(So alphabet positions increase by 3 each time — valid pattern)} \\[10pt]\textbf{Numeric pattern:} \\\text{Check how the numbers increase:} \\\quad 4 \rightarrow 8 \rightarrow 12 \rightarrow 32 \rightarrow 64 \\[5pt]\quad 4 \times 2 = 8 \\ \quad 8 \times 2 = 16 \\\quad 16 \times 2 = 32 \\\quad 32 \times 2 = 64$$​​
