Given series: D8, G14, J20, M26, ?
Here the pattern is as follows:
The alphabets are following the pattern as below:
And the numbers in each term are obtained by multiplying the positional value of the corresponding alphabets by 2.
Following this pattern, the last element will be P32 as the position of P is 16 and16 × 2 = 32.
Hence, P32 is the correct answer.
