By identifying the number series question pattern, we see that,
\(\displaystyle 1.5\times 2+{{1}^{2}}=4\)
\(\displaystyle 4\times 4+{{2}^{2}}=20\)
\(\displaystyle 20\times 6+{{3}^{2}}=126\)
\(\displaystyle 126\times 8+{{4}^{2}}=1048\)
\(\displaystyle 1048\times 10+{{5}^{2}}=10505\)

Answer: (c)
By identifying the number series MCQ pattern, we see that,
\(\displaystyle 89250\div 5=17850\)
\(\displaystyle 17850\div 2.5=7140\)
\(\displaystyle 7140\div 5=1428\)
\(\displaystyle 1428\div 2.5=571.2\)
\(\displaystyle 571.2\div 5=114.24\)

(a) 239
(b) 225
(c) 264
(d) 235
(e) None of these
Answer: (e)
By identifying the number series MCQ pattern, we see that,
\(\displaystyle 104+{{7}^{2}}=153\)
\(\displaystyle 153+{{6}^{2}}=189\)
\(\displaystyle 189+{{5}^{2}}=214\)
\(\displaystyle 214+{{6}^{2}}=230\)
3 1731 ? 3243 3459 3523
(a) 2371
(b) 2731
(c) 3731
(d) 3127
(e) None of these
Answer: (b)
By identifying the MCQ on number series, we see that,
\(\displaystyle 3523-3459=64={{4}^{3}}\)
\(\displaystyle 3459-3243=216={{6}^{3}}\)
\(\displaystyle ?=3243-{{8}^{3}}=3243-512=2731\)
\(\displaystyle 2731-1731=1000={{10}^{3}}\)
\(\displaystyle 1731-3=1728={{12}^{3}}\)
10 18 34 ? 130 258
(a) 32
(b) 60
(c) 66
(d) 68
(e) None of these
Answer: (c)
By identifying the MCQ on number series, we see that,
\(\displaystyle 10\times 2-2=20-2=18\)
\(\displaystyle 18\times 2-2=36-2=34\)
\(\displaystyle 34\times 2-2=68-2=66\)
\(\displaystyle 66\times 2-2=132-2=130\)
4 10 33 136 ? 4116
(a) 822
(b) 534
(c) 685
(d) 745
(e) 548
Answer: (c)
By identifying the MCQ on number series, we see that,
\(\displaystyle 4\times 2+2=10\)
\(\displaystyle 10\times 3+3=33\)
\(\displaystyle 33\times 4+4=136\)
\(\displaystyle 136\times 5+5=680+5=685\)
0.5, 0.55, 0.65, 0.8, ?
(a) 0.9
(b) 0.82
(c) 1
(d) 0.95
(e) None of these
Answer: (c)
By identifying the MCQ on number series, we see that,
The pattern is +0.05, +0.10, +0.15,…….
So, missing term = 0.8 + 0.20 = 1
5, 6, 10, 19, 35 ?
(a) 50
(b) 55
(c) 60
(d) 71
(e) None of these
Answer: (c)
By identifying the MCQ on number series,
Add \(\displaystyle {{1}^{2}},{{2}^{2}},{{3}^{2}},{{4}^{2}},{{5}^{2}}\) etc.
5 6 14 45 ?
(a) 183
(b) 185
(c) 138
(d) 139
(e) 184
Answer: (e)
By identifying the MCQ on number series, the pattern followed is
\(\displaystyle 5\times 1+1=6\)
\(\displaystyle 6\times 2+2=14\)
\(\displaystyle 14\times 3+3=45\)
\(\displaystyle 45\times 4+4=184\)
