Number Series Questions for Bank Exams PDF with answers.

Solutions (1 to 10)

1) Answer (e)

The pattern in the series is,
$17+1\times2=19$.
$19+2\times3=25$.
$25+3\times4=37$.
$37+4\times5=57$.
$57+5\times6=87$.
Hence, Option E is the correct answer.

2) Answer (a)

The pattern in the series id,
$61 + 21 = 82$.
$82 + (21\times2) = 82 + 42 = 124$.
$124 + (21\times3) = 124 + 63 = 187$.
$187 + (21\times4) = 187 + 84 = 271$.
$271 + (21\times5) = 271 + 105 = 376$.
Hence, Option A is the correct answer.

3) Answer (e)

The pattern followed by series is,
Hence the next term will be = 61+36+141.
=$238$. Therefore, Option E is correct.

4) Answer (e)

The series follows a pattern:
$179+1^{3}=180$.
$180-2^{3}=172$.
$172+3^{3}=199$.
$199-4^{3}=135$.
Hence, Next term in the series will be = $135+5^{3}=260$.
Therefore, Option E is correct.

5) Answer (a)

14,6,5,6.5,12,?
Let unknown quantity be’x’.
The series is $(14\times0.5 – 1), (6 \times1 – 1), (5\times1.5 – 1), (6.5\times2 – 1),……$.
Hence,$x=12\times2.5-1$.
$x=29$.
Hence, Option A is correct.

6) Answer (e)

Consecutive natural numbers are added

8 $\times 1$ = 8
8 $\times 2$ = 16
16 $\times 3$ = 48
48 $\times 4$ = 192
192 $\times 5$ = 960

7) Answer (c)

Multiples of 0.05 are alternatively added and subtracted

16.8 $+ 0.05 \times 1$ = 16.85
16.85 $- 0.05 \times 2$ = 16.75
16.75 $+ 0.05 \times 3$ = 16.9
16.9 $- 0.05 \times 4$ = 16.7
16.7 $+ 0.05 \times 5$ = 16.95

8) Answer (c)

The pattern is :

8 + $12$ = 20
20 + $12 + 3$ = 35
35 + $12 + 3 + 4$ = 54
54 + $12 + 3 + 4 + 5$ = 78
78 + $12 + 3 + 4 + 5 + 6$ = 108

 

9) Answer (d)

The pattern is :

16 $\times 2$ = 32
32 $\times 1$ = 32
32 $\times \frac{1}{2}$ = 16
16 $\times \frac{1}{4}$ = 4
4 $\times \frac{1}{8}$ = 0.5

10) Answer (c)

Square of odd numbers are added

63 $+ 3^2$ = 72
72 $+ 5^2$ = 97
97 $+ 7^2$ = 146
146 $+ 9^2$ = 227
227 $+ 11^2$ = 348
