1 Answer 1


My answer is:

G and 11


On each section, there are two alternating formats:

A(1) Y(25) C(3) - 26
E(5) U(21) ?(?) - 22
I(9) Q(17) K(11) - 18

X(24) D(4) V(22) - 3
T(20) H(8) R(18) - 7
P(16) L(12) N(14) - ?

As you can see, with the first format, from the first letter to the third, the index of the letter is increased by 2. Also, from the second letter to the number in the middle, the index is increased by 1.
With the second format, the opposite is true (first and third letters are decreased by 2, second letter and middle number are decreased by 1). With that, the missing values that satisfy the pattern are:

E(5) U(21) G(7) - 22
P(16) L(12) N(14) - 11
