Missing Numbers Quiz Set 030

The sequence in each column vertically is : (5 + 4) x 2 = 18; (2 + 4) x 5 = 30; (4 + 7 ) x 3 = 33 so on.

10 → (1)² + (0)², 41 → (2)² + (1)², 94 → (3)² + (2)², 2516 → (5)² + (4)², 3625 → (6)² + (5)², 4936 → (7)² + (6)² but in 1624 it is not so.

The series is: (1 + 1) X 1 = 2, then (2 + 1) X 2 = 6, then (6 + 1) X 3 = 21, then (21 + 1) X 4 = 88, not 86.

The elements are moving in clockwise direction as 3; (3)² = 9; (9)² = 81; (81)² = 6561

Number 3468 is wrong and should be replaced by 5184. The series is 3 X 3 = 9, then 9 X 4 gives 36, then 36 X 2 gives 72, then 72 X 3 gives 216, then 216 X 4 gives 864, then 864 X 2 gives 1728, then 1728 X 3 should give 5184, not 3468.
