52
Explanation:
The given sequence is a combination of two series :I. 3, 7, 13, 21, 31, ? and II. 4, 7, 13, 22, 34The pattern in I is + 4, + 6, + 8, + 10,…..The pattern in II is + 3, + 6, + 9, + 12,…..
So, missing term = 31 + 12 = 43.
4480.198, 194, 185, 169, ?
92
112
136
144
Explanation:
The pattern is – 4, – 9, – 16,…..i.e. – 22, – 32, – 42,…..So, missing pattern = 169 – 52 = 169 – 25 = 144.
4481.2, 3, 5,7,11,?, 17
12
13
14
15
Explanation:
Clearly, the given series consists of prime numbers starting from 2. So, the missingterm is the prime number after 11, which is 13.
4482.6, 12, 21, ?, 48
33

40
45
Explanation:
The pattern is + 6, + 9, + 12, + 15, …..So, missing term = 21 + 12 = 33.
4483.Which term of the series 5, 10, 20, 40, ….. is 1280?
10th
9th
8th
None of these
Explanation:
Clearly, 5 x 2 = 10, 10 x 2 = 20, 20 x 2 = 40,…..So, the series is a G.P. in which a = 5 and r = 2.Let 1280 be the rath term of the series.Then, 5×2n-1 = 1280 2n-1 = 256 = 28 n – 1 = 8 n = 9.
4484.2, 5, 9, ?, 20, 27
14
16
18
24
Explanation:
The pattern is + 3, + 4, + 5, + 6,…..So, missing term = 9 + 5 = 14.
4485.2, 3, 3, 5, 10, 13, ?, 43, 172, 177
23
38
39
40
Explanation:
The pattern is + 1, x 1, + 2, x 2, + 3, x 3, + 4, x 4, + 5.So, missing term = 13 x 3 = 39.
4486.9, 27, 31, 155, 161, 1127, ?
316
1135
1288
2254
Explanation:
The pattern is x 3, + 4, x 5, + 6, x 7,…..So, missing term = 1127 + 8 = 1135.
4487.2, 1, 2, 4, 4, 5, 6, 7, 8, 8, 10, 11, ?
9
10
11
12
Explanation:
The given sequence is a combination of three series :I. 1st, 4th, 7th, 10th, 13th terms i.e. 2, 4, 6, 8, ?II. 2nd, 5th, 8th, 11th terms i.e. 1, 4, 7, 10III. 3rd, 6th, 9th, 12th terms i.e. 2, 5, 8, 11
Clearly, I consists of consecutive even numbers. So, the missing term is 10.
4488.Which of the following will not be a number of the series 1, 8, 27, 64, 125,…..?
256
512
729
1000
Explanation:
The given series consists of cubes of natural numbers only. 256 is not the cube ofany natural number.
4489.1, 1, 2, 6, 24, ?, 720
100
104
108
120
Explanation:
The pattern is x 1, x 2, x 3, x 4,…..So, missing term = 24 x 5 = 120.
4490.2, 15, 4, 12, 6, 7, ?, ?
8, 8
8, 0
3, 8
None of these
Explanation:
Let the missing terms of the series be x1 and x2.Thus, the sequence 2, 15, 4, 12, 6, 7, x1 x2 is a combination of two series :I. 2, 4, 6, x1 and II. 15, 12, 7, x2I consists of consecutive even numbers.
So, missing term, x1 = 8.
The pattern in II is – 3, – 5,……So, missing term, x2 = 7 – 7 = 0.
4491.4832, 5840, 6848, ?
7815
7846
7856
7887
Explanation:
The pattern is + 1008.So, missing term – 6848 + 1008 = 7856.
4492.5824, 5242, ?, 4247, 3823
4467
4718
4856
5164
Explanation:
Each term in the series is obtained by subtracting from the preceding term the numberformed by the first three digits of the preceding term.So, missing term = 5242 – 524 = 4718.
4493.2, 8, 16, 128, ?
2042
2046
2048
2056
Explanation:
Each term in the series, except the first two terms, is the product of the preceding two terms.So, missing term = 16 x 128 = 2048.
4494.1, 2, 6, 7, 21, 22, 66, 67, ?
70
134
201
301
Explanation:
The pattern is + 1, x 3, + 1, x 3, + 1, x 3, + 1,…..So, missing term = 67 x 3 = 201.
4495.0.5, 0.55, 0.65,0.8,?
0.9
0.82
1
0.95
Explanation:
The pattern is + 0.05, + 0.10, + 0.15,…..So, missing term = 0.8 + 0.20 = 1.
4496.0, 2, 3, 5, 8, 10, 15, 17, 24, 26, ?

Explanation:
The given sequence is a combination of two series :I. 0, 3, 8, 15, 24, ? and II. 2, 5, 10, 17, 26The pattern in each one of I and II is + 3, + 5, + 7, + 9, …..
So, missing term = 24 + 11 = 35.
