Choose the number from the given options that will replace the question mark (?) in the following series:
दिए गए विकल्पों में से वह संख्या चुनें जो निम्नलिखित में प्रश्नचिंह ( ? ) के स्थान पर आएगी ?
121, 169, 225, 289, ?
Detailed Solution & Logic
Correct Answer:
361
The series is of perfect squares:
121 = $11^2$
169 = $13^2$
225 = $15^2$
289 = $17^2$
So the pattern is squares of consecutive odd numbers: 11, 13, 15, 17, 19
Next term = $19^2 = 361$
So, the correct answer is 361.
