Final answer:

The number seventy (70) is not a prime number; it is an even number and a composite number, as it has multiple divisors and the last digit is 0.

Step-by-step explanation:

The number seventy (70) can be analyzed based on its mathematical properties. Specifically, to determine whether 70 is a prime number, an even number, an odd number, or a composite number, we look at its divisibility.

A prime number is a number that has exactly two distinct positive divisors: 1 and itself. However, 70 can be divided by 1, 2, 5, 7, 10, 14, 35, and 70, indicating that it has more than two divisors. Hence, 70 is not a prime number.

When determining if a number is even or odd, we look at the last digit. If the last digit is 0, 2, 4, 6, or 8, it is even; otherwise, it is odd. Since the last digit of 70 is 0, it is an even number.

Since 70 has more than two divisors and is not a prime number, it is, in fact, a composite number. It is composed of other numbers multiplies together (like 2 x 35, or 7 x 10).
