Identify the relationship as square of the first number: x: x². Square 18 directly to get the result.
Analyze the relationship between 14 and 196
Calculate the square of the first term: 14 multiplied by 14 equals 196.
Apply the same logic to the second pair
Calculate the square of the given term 18: 18 multiplied by 18 equals 324.
B: 342 is not the square of 18 (18² = 324); C: 360 is not the square of 18; D: 288 is not the square of 18.
