What should come in place of the question mark (?) in the given series?
दी गई श्रृंखला में प्रश्नचिह्न (?) के स्थान पर क्या आना चाहिए?
89 87 84 79 72 ?
Detailed Solution & Logic
Correct Answer:
61
श्रृंखला: 89, 87, 84, 79, 72, ?
अंतर देखें:
89 → 87 = −2
87 → 84 = −3
84 → 79 = −5
79 → 72 = −7
घटने वाली संख्याएँ हैं:
2, 3, 5, 7 (अभाज्य संख्याएँ)
अगली अभाज्य संख्या = 11
