Answer :
To find the odd one out among the given numbers: 169, 196, 225, 289, and 324, let's determine if there's a pattern.
169: This number is a perfect square. [tex]169 = 13^2[/tex].
196: This number is also a perfect square. [tex]196 = 14^2[/tex].
225: This is a perfect square too. [tex]225 = 15^2[/tex].
289: This number is a perfect square. [tex]289 = 17^2[/tex].
324: This is a perfect square. [tex]324 = 18^2[/tex].
All the numbers except 196 ([tex]14^2[/tex]) follow the sequence of perfect squares of consecutive numbers: 13, 15, 17, and 18.
Therefore, the odd one out is 196, as it does not fit into the perfect squares of consecutive numbers in this list.
Correct answer: B) 196.
