   A. 168
   B. 172
   C. 174
   D. 175
   E. None
   
   Answer

   Answer – D. 175
   Solution:
   6*1 + 1² = 7
   7 * 3 + 3² = 30
   30 * 5 + 5² = 175
   175 * 7 + 7² = 1274
   
   
2. 10, 12, 15, 25, 40, 66, ?
   A. 100
   B. 101
   C. 102
   D. 103
   E. None
   
   Answer

   Answer – B. 101
   Solution:
   10 + (1² + 1) = 12
   12 + (2² – 1) = 15
   15 + (3² + 1) = 25
   25 + (4² – 1) = 40
   40 + (5² + 1) = 66
   66 + (6² – 1) = 101
   
   
3. 8, ?, 18, 44, 92, 174
   A. 9
   B. 10
   C. 11
   D. 12
   E. None
   
   Answer

   Answer – B. 10
   Solution:
   8+ (1² + 1) = 10
   10+ (3² – 1) = 18
   18+ (5² + 1) =44
   44+ (7² – 1) = 92
   92 + (9² + 1) = 174
   
   
4. 10, 15, 38, 123, ?, 2505
   A. 400
   B. 500
   C. 550
   D. 600
   E. None
   
   Answer

   Answer – B. 500
   Solution:
   10*1 + (1*5) =15
   15 *2 + (2*4) =38
   38 *3 + (3*3) = 123
   123*4 + (4*2) =500
   500*5 + (5*1) = 2505
   
   
5. 516 , ? , 505, 538, 494, 549
   A. 525
   B. 526
   C. 527
   D. 528
   E. None
   
   Answer

   Answer – C. 527
   Solution:
   516+11 = 527
   527-22 =505
   505+33 = 538
   538-44 = 494
   494+55 =549
