The input is a sequence of integers from 1 to 50. Here are some key observations and calculations about this range:

1. Basic Statistics

• Count: 50 numbers
• Sum: $\frac{50×51}{2} = 1275$
• Average: $\frac{1275}{50} = 25.5$

2. Even vs. Odd

• Even numbers: 2,4,...,50 → 25 numbers
• Odd numbers:1,3,...,49 →25 numbers

3. Prime Numbers

Primes between 1-50: 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47 → 15 primes

4. Squares & Cubes

• Perfect squares: 1²=1,2²=4,...,7²=49 → 1,4,9,16,25,36,49 → 7 squares
• Perfect cubes:1³=1,2³=8,3³=27 → 3 cubes (4³=64 is beyond 50)

If you had a specific question about these numbers (e.g., factorials, multiples of a number), feel free to clarify!
