There is a series of numbers which follow some definite order. Find the missing term and complete the series.
3, 4, 5, 5, 12, 13, 7, 24, 25, 9, ?, 41
The given numbers are in the set of three numbers which are Pythagorean triplet.
3^{2} + 4^{2} = 5^{2}, 5^{2} + 12^{2} = 13^{2},
7^{2} + 24^{2} = 25^{2}, 9^{2 }+ 40^{2} = 41^{2}.
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
10, 17, 26, 37, 50, …. ?
The pattern of the given series is
3^{2} + 1 = 10; 4^{2} + 1 = 17; 5^{2} + 1 = 26;
6^{2} + 1 = 37; 7^{2} + 1 = 50;
∴ 8^{2} + 1 = 65.
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
2, 4, 4, 8, 16, 16, 256, ?
∴ ? = 32
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
1, 5, 7, 14, 18, 20, 40, 44, 46, ?
1 + 4 = 5; 5 + 2 = 7; 7 × 2 = 14
14 + 4 = 18; 18 + 2 = 20; 20 × 2 = 40
40 + 4 = 44; 44 + 2 = 46; 46 × 2 = 92
∴ ? = 92
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
5, 12, 7, 15, 8, 18, 10, ?
Second, fourth, sixth terms are multiplies of 3 as, 12, 15, 18 and so on the eightterm will be 21.
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
325, 259, 204, 160, 127, 105, ?
325 – 66 = 259; 259 – 55 = 204;
204 – 44 = 160; 160 – 33 = 127;
127 – 22 = 105; 105 – 11 = 94;
∴ ? = 94
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
0, 2, 3, 5, 8, 10, 15, 17, 24, 26, ?
∴ ? = 35
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
120, 99, 80, 63, 48, ?
Here
120 – 21 = 99; 99 – 19 = 80; 80 – 17 = 63;
63 – 15 = 48; 48 – 13 = 35;
∴ ? = 35
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
1, 1, 4, 8, 9, 27, 16, ?
∴ ? = 64
There is a series of numbers which follow some definite order. Find the missing term and complete the series.
10, 14, 26, 42, 70, ?
10 + 14 + 2 = 26; 14 + 26 + 2 = 42;
26 + 42 + 2 = 70; 42 + 70 + 2 = 114;
∴ ? = 114
In each of the following questions, one term in the number series is wrong. Find out the wrong term.
196, 169, 144, 121, 101.
196 = 14^{2}; 169 = 13^{2}; 144 = 12^{2};
121 = 11^{2}; 10^{2} = 100;
∴ 101 is wrong term.
In each of the following questions, one term in the number series is wrong. Find out the wrong term.
2, 6, 24, 96, 285, 568, 567
2 × 6 – 6 = 6; 6 × 5 – 5 = 25;
25 × 4 – 4 = 96; 96 × 3 – 3 = 285;
285 × 2 – 2 = 568; 568 × 1 – 1 = 567;
∴ 24 is odd.
In each of the following questions, one term in the number series is wrong. Find out the wrong term.
93, 309, 434, 498, 521, 533
93 + 6^{3} = 309; 309 + 5^{3} = 434;
434 + 4^{3} = 498; 498 + 3^{2} = 525;
525 + 2^{3} = 533;
∴ 521 is wrong term.
In each of the following questions, one term in the number series is wrong. Find out the wrong term.
3, 2, 8, 9, 13, 22, 18, 32, 23, 42
2 + 10 = 12
∴ 9 is the wrong term.
In each of the following questions, one term in the number series is wrong. Find out the wrong term.
8, 13, 21, 32, 47, 63, 83
8 + 5 = 13; 13 + 8 = 21;
21 + 11 = 32; 32 + 14 = 46;
46 + 17 = 63; 63 + 20 = 83;
∴ 47 is odd.
