Choose the correct alternative from the given ones that will complete the series:
Directions: In the following Four questions, a series is given with one (or more) term missing. Choose the correct alternative from the given ones that will complete the series:
- C4X, F9U, I16R, ?
(a) L25P
(b) L25U
(c) L27P
(d) K25P - 15, 21, 57, ____, 221
(a) 96
(b) 108
(c) 121
(d) 126 - 720, 180, 176, 44, 40, 10, ___
(a) 6, 2
(b) 4, 2
(c) 6, 4
(d) 8, 6 - 5, 10, 20, 40, 80, ___
(a) 120
(b) 140
(c) 150
(d) 160
- L25O (All options are wrong)
Explanation:-
C (3) + 3 = F (6), 4 + 5 = 9 & X – 3 = U,
F (6) + 3 = I ((9), 9 + 7 = 16 & U – 3 = R,Same as,
I (9) + 3 = L (12), 16 + 9 = 25 & R – 3 = O.Then, the next term will be L25O.
Hence, the correct answer is L25O.
- (c) 121
Explanation:-
- (a) 6, 2
Explanation:-
720 / 4 = 180, 180 – 4 = 176, 176/4 = 44, 44 – 4 = 40, 40/4 = 10,
Same as,
10 – 4 = 6 & 6/4 = 1.5
= 2 (Approx)
Then, the next number is 6, 2.Hence, the correct answer is option (a) 6, 2.
- (d) 160
Explanation:-
5 x 2 = 10, 10 x 2 = 20, 20 x 2 = 40, 40 x 2 = 80,Same as,
80 x 2 = 160.Then, the next number will be 160.
Hence, the correct answer is option (d) 160.
Excuse me!! where is the explanation of question no.2 ???
