(a) 192
(b) 182
(c) 186
(d) 198
(e) None of these
Solution: (a)
The pattern of the series is as follows:
\(\displaystyle 3\times 2=6\)
\(\displaystyle 6\times 2=12\)
\(\displaystyle 12\times 2=24\)
\(\displaystyle 24\times 2=48\)
\(\displaystyle 48\times 2=96\)
\(\displaystyle 96\times 2=192\)
2 16 112 672 3360 13440 ?
(a) 3430
(b) 3340
(c) 40320
(d) 43240
(e) None of these
Solution: (c)
\(\displaystyle 2\times 8=16\)
\(\displaystyle 16\times 7=112\)
\(\displaystyle 112\times 6=672\)
\(\displaystyle 672\times 5=3360\)
\(\displaystyle 3360\times 4=13440\)
\(\displaystyle 13440\times 3=40320\)
? = 40320
4 9 19 ? 79 159 319
(a) 59
(b) 39
(c) 49
(d) 29
(e) None of these
Solution: (c)
Given number series MCQ
\(\displaystyle 4\times 2+1=9\)
\(\displaystyle 9\times 2+1=19\)
\(\displaystyle 19\times 2+1=39\)
\(\displaystyle 39\times 2+1=79\)
\(\displaystyle 79\times 2+1=159\)
\(\displaystyle 159\times 2+1=319\)
? = 39
588 563 540 519 ? 483 468
(a) 500
(b) 496
(c) 494
(d) 490
(e) None of these
Solution: (a)
\(\displaystyle 588-25=563\)
\(\displaystyle 563-23=540\)
\(\displaystyle 540-21=519\)
\(\displaystyle 519-19=500\)
\(\displaystyle 500-17=483\)
\(\displaystyle 483-15=468\)
? = 500

(a) 92
(b) 114
(c) 98
(d) 100
(e) None of these
Solution: (d)
Given number series
\(\displaystyle 121={{11}^{2}}\)
\(\displaystyle 100={{10}^{2}}\)
\(\displaystyle 81={{9}^{2}}\)
\(\displaystyle 64={{8}^{2}}\)
\(\displaystyle 49={{7}^{2}}\)
\(\displaystyle 36={{6}^{2}}\)
