Question

Complete the series by replacing '?' mark.
G4T, J9R, M20P, P43N, S9OL, ?

• A. S90L
• B. V185J
• C. M20P
• D. P43N

Answer 1

Answer: (B)

V185J

We have to replace ${}^{\prime }{?}^{\prime }$ in the following series $G4T,J9R,M20P,P43N,S90L,?$

For $1^{st}$ term
$G+3=J$
$J+3=M$
$M+3=P$
$P+3=S$

$S+3=V$
For $3^{rd}$ term
$T-2=R$
$R-2=P$
$P-2=N$
$N-2=L$

$L-2=J$

For $2^{nd}$ term
$4\times 2+1=9$
$9\times 2+2=20$
$20\times 2+3=43$
$43\times 2+4=90$

$90\times 2+5=185$

Hence the last term is $V185J$
