Answers With Explanatios :
1. Multiplied by 2 & increased by 3
2 = 26, 26 + 3 = 29´ 2= 10, 10 +3 = 13, 13 ´5
2 = 122´There for missing number is 61
2. 13 + 1, 23 + 1, 33 +1, 43 + 1, 53 + 1
There for missing number is 63 + 1= 217.
3. Difference between consecutive no; increased by 1
2 +3 + 4 + 5---------
There for missing number is 16 + 6 = 22.
4. It is a combination of two series = 5, 6, 7, & 9, 11, (--------)
There for missing number is 11+ 2 = 13.
5. Series consists of Prime no:.
There for missing number is 43.
6. Sequence is – 11 , – 13 , – 15 , – 13------------
There for missing number is 45 – 11 = 34.
7. Sum of any three consecutive terms of the series gives the next term.
Thus, 1 +3 +4 = 8; 3+4+8 = 15; 4+8+15= 27 & so on.
There for missing number is 8+ 15 +27 = 50.
8. 33 is subtracted from each term of the series to obtain the next term.
There for missing number is 113 – 33 = 80
9. The sequence is +8, +8, +16, +16, +24----------
There for missing number is 73 + 24 = 97
10. The sequence is +3, +6, +12, +24, ------------
There for missing number is 47 9 +48 = 95.
11. Alternately we add 3 & subtract 1.
Thus 9 +3=12, 12 – 1 = 11, 11+3 = 14 & so on.
There for missing number is 13+3= 16.
12. In each term 15 multiplied a prime no. i. e.
23,´ 19, 15´17, 15´13, 15´ 11, 15´15
29 = 435.´There for missing number is = 15
13. The sequence is +5, +8, +11, +14, +17, +20
There for 47 breaks this sequence & The correct sequence is =46
14 Suppose the terms of the series as A, B, C, D-------------
3+1´2+1, D´3+ 1, C´2+1, B´Then the sequence is A
There for wrong number is 356.
15. Each term at even place in the series, except 100 is obtained multiplying the preceding term by 2.
There for wrong number is 100 & the correct term is 96.
16 each number in the series is multiplied by 2 & the result is increased by 1 to obtain the next number
17 The no. are cube of prime number , i.e 23 , 33 , 53 , 73 ----------------
18 The sequence is , +7 , +5 , + 7 , + 5
19 The sequence is , +5 , + 8 , + 11 , + 14 , +17 , +30
20 The correct sequence is 52 , 72 , 92 , --------------------
21 The sequence is , +12 , +22 , +32 , ------------------
22 The nos. are 12 + 1 , 22 + 1 , -------------------------
23 The terms are successively divided by 12 , 10 , 8 , 6
24 The sequence is , – 1 , – 3 , – 5 , -----------------------
25 The sequence is , – 20 , – 25 , – 30 , – 35 --------------
26 The sequence is , – 66 , – 55 , – 44 , ----------------
27 The sequence is , +2 , +4 , + 6
28 The sequence is , +1 , – 2 , +3 , – 4 , ------------------
29 The sequence is as follows
2nd term = ( 1st term + 1) 1
3rd term = ( 2nd term + 1 ) 2 etc
30 The sequence is ( 14 )2 , ( 13)2 , (12)2 , (11)2 , (10)2
