Download Solution PDFगणना:
154 - 147 = 7
147 - 136 = 11
136 - 123 = 13
123 - 106 = 17
क्रमागत पदों के बीच अंतर 7, 11, 13 और 17 हैं। ये अंतर अभाज्य संख्याओं द्वारा बढ़ रहे हैं।
अगला अंतर 5 होना चाहिए (7 से पहले की अभाज्य संख्या)।
अब, लुप्त संख्या ज्ञात करने के लिए 154 में 5 जोड़ें:
154 + 5 = 159
∴ श्रेणी में लुप्त पद 159 है।
