| Direction: In these questions, a series is given with one term missing. Choose the correct alternative that will complete the series. |
| 563, 647,479, 815, ? |
A) 672
B) 386
C) 279
D) 143
Correct Answer: D
Solution :
The pattern is +84, -168, +336, -672, ... i.e., \[+(84\times {{2}^{0}}),\,-(84\times {{2}^{1}}),\,\,+\,(84\times {{2}^{2}})\] So, missing term is 815-672 = 143.
