Question
The three numbers in each group are related in the same way.Choose the number that completes the last group.( 4 [ 6 ] 16 )( 3 [ 8 ] 19 )( 6 [ ? ] 14 )A2B8C11D1E4
Solution
The relationship in the first group is 4 * 4 - 10 = 6 and 4 * 4 + 2 = 16. The relationship in the second group is 3 * 3 - 1 = 8 and 3 * 3 + 10 = 19. So, the relationship in the third group should be 6 * 6 - x = ? and 6 * 6 - 22 = 14. Therefore, x = 36 - 14 = 22. So, the answer is B8.
