11 - 9 = 2
15 - 11 = 4
23 - 15 = 8
39 - 23 = 16
The differences are 2, 4, 8, and 16, which are powers of 2 (2^1, 2^2, 2^3, 2^4).
Following this pattern, the next difference should be 2^5 = 32.
The last number in the series:
39 + 32 = 71
11 - 9 = 2
15 - 11 = 4
23 - 15 = 8
39 - 23 = 16
अंतर 2, 4, 8, और 16 हैं, जो 2 की घातें हैं (2^1, 2^2, 2^3, 2^4)।
इस पैटर्न के बाद, अगला अंतर 2^5 = 32 होना चाहिए।
श्रृंखला में अंतिम संख्या:
39 + 32 = 71
