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.
So, missing term = 31 + 12 = 43.

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.

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.
Clearly, I consists of consecutive even numbers. So, the missing term is 10.

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

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.
So, missing term, x1 = 8.
The pattern in II is – 3, – 5,……So, missing term, x2 = 7 – 7 = 0.

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.
