Answer:
The sum of n successive odd number is 48, if n = 6.
Step-by-step explanation:
Let us figure it out with trial and error:
- 3 = 3 ≠ 48. ( So, n ≠ 1. )
- 3 + 5 = 8 ≠ 48. ( So, n ≠ 2. )
- 3 + 5 + 7 = 15 ≠ 48. ( So, n ≠ 3. )
- 3 + 5 + 7 + 9 = 24 ≠ 48. ( So, n ≠ 4. )
- 3 + 5 + 7 + 9 + 11 = 35 ≠ 48. ( So, n ≠ 5. )
- 3 + 5 + 7 + 9 + 11 + 13 = 48. ( Thus, n = 6. )
