Which of the following terms will replace the question mark (?) in the given series to make it logically complete?
TGB 6, VED 18, XCF 30, ZAH 42, BYJ 54,?

Series: TGB 6, VED 18, XCF 30, ZAH 42, BYJ 54, ?​

Logic: First Letter Move forward by 2 positions each time, Second Letter Move backward by 2 positions each time, Third Letter Move forward by 2 positions each time, Numbers letter Add 12 each time

T+2= V, G-2= E, B+2= S, 6+12= 18

V+2= X, E-2=C, D+2=F, 18 +12=30

X+2=Z, C-2=A, F+2=H, 30+12 = 42

Z+2=B, A-2=Y, H+2=J 42+12= 54

B+2=D, Y-2=W, J+2=L 54+12 = 66

The term that will replace the question mark is DWL 66.

Thus, correct answer is (d) DWL 66​​
