Number series. Numerical Reasoning questions. Test 01

In each of the following questions a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and fill in the blank spaces.

2, 7, 14, 23, ?, 47
The given sequence is +5, +7, +9, ——
ie. 2+ 5 = 7, 7 + 7 = 14, 14 + 9 = 23
Missing Number = 23 + 11 = 34.
4, 6, 12, 14, 28, 30, ?
The given sequence is a combination of two series 4, 12, 28, .... and 6, 14, 30, .... The pattern is +8, +16, +32. So, the missing number = (28 + 32) = 60
4, 9, 13, 22, 35, ?
Sum of two consecutive numbers of the series gives the next number.
11, 13, 17, 19, 23, 29, 31, 37, 41, ?
The series consists of prime numbers.
15, 31, 63, 127, 255, ?
Each number is double of the preceding one plus 1.
5, 11, 17, 25, 33, 43, ?
The sequence is +6, +6, +8, +8, +10, ....
9, 12, 11, 14, 13, ?, 15
Alternatively, 3 is added and one is subtracted.
0.5, 0.55, 0.65, 0.8, ?
The pattern is + 0.05, + 0.10, + 0.15, .....
1, 4, 9, 16, 25, ?
The sequence is a series of squares, 1², 2², 3², 4², 5²....
2, 1, (1/2), (1/4), ?
This is a simple division series; each number is one-half of the previous number.
