• Directions:(1-5) What should come in place of the question mark (?) in the following number series?

##### 1. Question

5, 8, 16, 39, 107, ?

Ans:4
The pattern is:

5×3 – 7 = 8, 8×3 – 8 = 16, 16×3 – 9 = 39, 39×3 – 10 = 107, 107×3 – 11 = 310

• ##### 2. Question

41, 43, 71, 73, 109, 111, ?

Ans:2
The series is 62+5, 72-6, 82+7, 92-8, 102+9, 112-10, 122+11

Hence the next term is 144+11=155

• ##### 3. Question

29, 36, 39, 45, 46, ?

Ans:1
The next term is obtained by adding the number to the difference of its digits.

29+7=36, 36+3=39, 39+6=45, 45+1=46, 46+2=48

• ##### 4. Question

908, 868, 814, 744, 656, ?

Ans:3
The pattern is:

908 – (8×5) = 868, 868 – (9×6) = 814, 814 – (10×7) = 744, 744 – (11×8) = 656.

So the next term is 656 – (12×9) = 548

• ##### 5. Question

7, 5, 14, 20, 42, 120, 210, ?

Ans:3
The odd terms are multiplied by 2, 3, 5 successively (prime no.s) while the even terms are multiplied by 4, 6, 8 successively (composite no.s).

7*2 = 14 (3rd term)

5*4 = 20 (4th term)

14*3 = 42 (5th term)

20*6 = 120 (6th term)

42*5 = 210 (7th term)

120*8 = 960 (8th term)

• ##### 6. Question

27, 76, 176, 345, 601, ?

Ans:5
The pattern is as follows:

27 + 72 = 76

76 + 102 = 176

176 + 132 = 345

345 + 162 = 601

601 + 192 = 962

• ##### 7. Question

28376, 24281, 20908, 18167, 15974, ?

Ans:1
The pattern is as follows:

28376 – 163 + 1 = 24281

24281 – 153 + 2 = 20908

20908 – 143 + 3 = 18167

18167 – 133 + 4 = 15974

15974 – 123 + 5 = 14251

• ##### 8. Question

31, 108, 612, 4832, 48220, ?

Ans:5
The pattern is as follows:

(31 – 4) x 4 = 108

(108 – 6) x 6 = 612

(612 – 8) x 8 = 4832

(4832 – 10) x 10 = 48220

(48220 – 12) x 12 = 578496

• ##### 9. Question

44, 133, 667, 4672, 51396, ?

Ans:4
The pattern multiplies with prime numbers to the previous term and adds an increasing constant as show below:

44 x 3 + 1 = 133

133 x 5 + 2 = 667

667 x 7 + 3 = 4672

4672 x 11 + 4 = 51396

51396 x 13 + 5 = 668153

• ##### 10. Question

7, 8, 33, 190, 1379, ?

Ans:2
The pattern is as follows:

(7 x 1) + 12 = 8

(8 x 3) + 32 = 33

(33 x 5) + 52 = 190

(190 x 7) + 72 = 1379

(1379 x 9) + 92 = 12492 #### About Study Virus
