Question:
Find the next number:
45, 150, 315, 540, 825, ?
अगली संख्या ज्ञात कीजिए:
45, 150, 315, 540, 825, ?
Options:
- 1170
- 1200
- 1215
- 1250
- 1170
- 1200
- 1215
- 1250
Correct Answer: a)
Explanation:
First differences: 150 – 45 = 105; 315 – 150 = 165; 540 – 315 = 225; 825 – 540 = 285.
Second differences: 165 – 105 = 60; 225 – 165 = 60; 285 – 225 = 60.
Next difference = \(285 + 60 = 345\).
Next term = \(825 + 345 = 1170\).
अंतर: 105, 165, 225, 285 (प्रत्येक बार +60)।
अगला अंतर = \(285 + 60 = 345\)।
अगली संख्या = \(825 + 345 = 1170\)।
