Detailed Explanation & Answer

Find the differences between terms:

8 - 3 = 5
15 - 8 = 7
24 - 15 = 9
35 - 24 = 11
48 - 35 = 13

We see that the differences are increasing by 2:
5, 7, 9, 11, 13 → next difference should be 15

Now add 15 to the last term:
48 + 15 = 63

So, the missing number is 63

पदों के बीच अंतर ज्ञात कीजिए:

8 - 3 = 5
15 - 8 = 7
24 - 15 = 9
35 - 24 = 11
48 - 35 = 13

हम देखते हैं कि अंतर 2 से बढ़ रहा है:
5, 7, 9, 11, 13 → अगला अंतर 15 होना चाहिए

अब अंतिम पद में 15 जोड़ें:
48 + 15 = 63

अतः, लुप्त संख्या 63 है

The Correct Answer is 3
