# Find the missing term :

1. QAR, RAS, SAT, TAU, _____UAV
(a) UAV                      (b) UAT                 (c) TAS                   (d) TAT
2. DEF, DEF2, DE2F2, _____, D2E2F3
(a) DEF3                         (b) D3EF3            (c) D2E3F              (d) D2E2F2
3. QPO, NML, KJI, ______, EDC
(a) HGF                           (b) CAB                 (c) JKL                    (d) GHI
4. JAK, KBL, LCM, MDN, _____
(a) OEP                            (b) NEO               (c) MEN                  (d) PFQ
5. BCB, DED, FGF, HIH, _____
(a) JKJ                             (b) HJH               (c) IJI                       (d) JHJ

Explanation:-
The position of A is middle in all terms,
And
Q + 1 = R,  R + 1 = S,  S + 1 = T,  T + 1 = U, U + 1 = V.

Then, the missing term is UAV.

Hence, the correct answer is option (a) UAV.

Explanation:-
DEF, DEF2, DE2F2,  same as , next term is D2E2F2.

Hence, the correct answer is option (d) D2E2F2.

Explanation:-
Q – 1 = P,  P – 1 = O.
O – 1 = N, N – 1 = M & M – 1 = L.
L – 1 = K,  K – 1 = J   &  J – 1 = I.
Similarly,
I – 1 = H, H – 1 = G & G – 1 = F.

Then, missing term is HGF.

Hence, the correct answer is option (a) HGF.

Explanation:-

J + 1 = K &  A + 1 = B.
K + 1 = L &  B + 1 = C.
L  + 1 = M & C + 1 = D.

Similarly,
M + 1 = N, N + 1 = O & D + 1 = E

Then, missing term is NEO.

Hence, the correct answer is option (b) NEO.

Explanation:-
B + 1 = C, C – 1 = B  &  C + 1 = D.
D + 1 = E, E – 1  = D  & E  + 1 = F.
F + 1 = G, G – 1 = F  & G + 1 = H.
H + 1 = I, I – 1 = H  & I + 1 = J.
J + 1 = K, K – 1 = J.

Then, missing term is JKJ.

Hence, the correct answer is option (a) JKJ.
