You are required to identify and decipher this pattern and accordingly find the missing character in the figure. Example 1: (a) 7 (b) 25 (c) 49 (d) 129 Solution. (b) The pattern is (16 – 6)2 + (5 – 2)2 = 102 + 32 = 109 (22 – 15)2 + (21 – 19)2 = 72 + 22 = 53 So, the missing number = (17 – 13)2 + (51 – 48)2 = 42 + 32 = 25 Inserting the Missing Character

(d) Moving clockwise direction, the numbers are 13 – 1 = 0, 23 – 1 = 7, 33 – 1 = 26 and 43 – 1 = 63 Example 3: (a) 9 (b) 18 (c) 24 (d) 27 Solution. (a) Starting from 3 and moving clockwise, the number in each quadrant is the square of that in the previous quadrant. So, the missing number = 32 = 9

(c) The pattern is 3 × 2 – 1 = 5, 5 × 2 – 2 = 8, 8 × 2 – 3 = 13 , 13 × 2 – 4 = 22 So, the missing number = 22 × 2 – 5 = 39 Example 5: (a) 5 (b) 12 (c) 13 (d) 26 Solution. (a) The pattern is 3 × 2 + 1 = 7, 5 × 2 + 1 = 11, 7 × 2 + 1 = 15 So, the missing number 2 × 2 + 1 = 5
