Directions (11-15): In the following number series only one number is wrong. Find out the wrong number.
Q11. 32 34 37 46 62 87 123
(a) 34
(b) 37
(c) 62
(d) 87
(e) 46
S11. Ans (a)
Sol.
The pattern of the number series is :
32 + 12 = 32 + 1 = 33
33 + 22 = 33 + 4 = 37
37 + 32 = 37 + 9 = 46
46 + 42= 46 + 16 = 62
62 + 52= 62 + 25 = 87
Wrong number= 34
So, there should be 33 instead of 34.
Q12. 7 18 40 106 183 282 403
(a) 18
(b) 282
(c) 40
(d) 106
(e) 183
S12. Ans (c)
Sol.
The pattern of the number series is :
7 + 1 × 11 = 7 + 11 = 18
18 + 3 × 11 = 18 + 33 = 51
51 + 5 × 11 = 51 + 55 = 106
106 + 7 × 11 = 106 + 77 = 183
183 + 9 × 11 = 183 + 99 = 282
Wrong number= 40
So, there should be 51 instead of 40.

(b) 829
(c) 808
(d) 788
(e) 745
S13. Ans (d)
Sol.
The pattern of the number series is :
850 – 1 × 7 = 843
843 – 2 × 7 = 829
829 – 3 × 7 = 808
808 – 4 × 7 = 780
780 – 5 × 7 = 745
745 – 6 × 7 = 703
Wrong number= 788
So, there should be 780 instead of 788.

(a) 321
(b) 465
(c) 573
(d) 537
(e) 590
S14. Ans (e)
Sol.
The pattern of the number series is :
33 + 288 = 321
321 + 144 = 465
465 + 72 = 537
537 + 36 = 573
573 + 18 = 591
591 + 9 = 600
Wrong number= 590
So, there should be 591 instead of 590.
Q15. 37 47 52 67 87 112 142
(a) 47
