Number Series Questions for Bank Exams PDF with answers.

SolutionsÂ (1Â toÂ 10)

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.

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.

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

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.

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.

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

Multiples of 0.05 are alternatively added and subtracted

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

The pattern isÂ :

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

The pattern isÂ :

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

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