Detailed explanation-1: -Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
Detailed explanation-2: -25, 36, 49, 64 and 81 are squares of 5, 6, 7, 8 and 9 respectively. The next number should be square of 10, which is 100. Hence, “100” is the correct answer.
Detailed explanation-3: -The correct sequence= 25, 49, 81, 121, 169, 225 So, 36 is the incorrect number.
Detailed explanation-4: -First, find the common difference for the sequence. Subtract the first term from the second term. Subtract the second term from the third term. To find the next value, add to the last given number.
Detailed explanation-5: -Answer: Answer: The missing value is 4.5 or 9/2.
