Question 125
Select the term from among the given options that can replace the question mark(?) in the following series.
D5f, n15P, H9j, j11L, L13n, f7H, P17r, ?
Solution
The middle number represents the numerical position of the middle letter of the other 2 letters.
The terms start with capital letters alternatively. As the given last term is P17r, the next term shouldn't start with capital letter.
Considering these 2 conditions, only b3D could be the next term.
