Question

Find the wrong term in the letter-number series given below:
G4T,J10R,M20P,P43N,S90L,

• A. G4T
• B. J10R
• C. M20P
• D. P43N
• E. S90L

Answer 1

The correct option is B J10R

The first letter of each term is moved three steps forward and the last letter moves two steps backward to get the corresponding letter of the next term The numbers follows the sequence $\times 2+1\times 2+2,\times 2+3,\times 2+4$
So, 10 is wrong must be replaced by $(4\times 2+1)=9$
