 # ZS-Associates Reasoning Question

DIRECTIONS for questions 1 to 4: What will come in place of question mark (?) in the given number series?
1. 15 27 37 45 51 ?
1. 158
2. 80
3. 65
4. 74
5. 55
Given series is: 15 27 37 45 51 ?
And the pattern is 27 – 15 = 12, 37 – 27 = 10, 45 – 37 = 8, 51 – 45 = 6.
2. 700 457 376 349 340 ?
1. 266
2. 329
3. 304
4. 337
5. 307
Given series is:
700 457 376 349 340 ?
Pattern is 700 – 457 = 243, 457 – 376 = 81, 376 – 349 = 27, 349 – 340 = 9
Thus, the next term is 340 – 3 = 337
1. 1 2 6 21 88 ?
1. 425
2. 475
3. 295
4. 445
5. 395
Given series is:
1 2 6 21 88 ?
Pattern is 1×1+1= 2
2×2+2= 6
6×3+3=21
21×4+4= 88
88×5+5= 445
So the next term of the series is = 445
2. 19 20 16 25 9 ?
1. 45
2. 55
3. 59
4. 34
5. 81
Given series is:
19 20 16 25 9 ?
Pattern is 19 – 20 = -1
20 – 16 = 4
16 – 25 = -9
25 – 9 = 16
So, next term of the series is = 9 – (-25) = 34
