Solution for the pattern: 3 3 4 8 10 36 ?
|
| Sequence Pattern: 3 3 4 8 10 36 ?Solution: Odd Sequence Starting from First : 3 4 10 ? Even Sequence Starting from Second : 3 8 36 Calculating Odd Sequence: (3 * 1) + 1 = 3 (4 * 2) + 2 = 10 (10*3) + 3 = 33 Ans Note: Multiplication is happening with consecutive numbers and so is the addition. Calculating Even Sequence: (3*2) + 2 = 8 (8*4) + 4 = 10 (10*6) + 6 = 66 Note: Multiplication is happening with even numbers and so is the addition.Hence the final sequence would be 3 3 4 8 10 36 33 (Ans) 66 |
