Directions : What will come in place of question mark (?) in the following series?
1
132     156     182     210       240       ?
» Explain it
A
Series Pattern  Given Series  
11 × 12 = 132 132  
12 × 13 = 156 156  
13 × 14 = 182 182  
14 × 15 = 210 240  
15 × 16 = 240 240  
16 × 17 = 272 272

Hence, option (A) is correct.
2
186     210     258     282       ?       354
» Explain it
B
Series Pattern  Given Series  
186 186  
186 + 24 = 210 210  
210 + 48 = 258 258  
258 + 24 = 282 282  
282 + 48 = 330 330
330 + 24 = 354 354  

Hence, option (B) is correct.
3
11     53     93     129       159       ?
» Explain it
C
Series Pattern  Given Series  
11 11  
11 + 42 = 53 53  
53 + 40 = 93 93  
93 + 36 = 129 129  
129 + 30 = 159 159  
159 + 22 = 181 181

Hence, option (C) is correct.
4
12     6     15     67.5       ?       3729.375
» Explain it
D
Series Pattern  Given Series  
12 12  
12 × 0.5 = 6 6  
6 × 2.5 = 15 15  
15 × 4.5 = 67.5 67.5  
67.5 × 6.5 = 573.75 438.75
438.75 × 8.5 = 6024.375 3729.375  

Hence, option (D) is correct.
5
383     394     407     414       419       ?
» Explain it
A
Series Pattern  Given Series  
383 383  
383 + (8 + 3) = 394 394  
394 + (9 + 4) = 407 407  
407 + (0 + 7) = 414 414  
414 + (1 + 4) = 419 419  
419 + (1 + 9) = 429 429

Hence, option (A) is correct.
