There are 45 even two-digit numbers. The smallest even two-digit number is 10, and the largest is 98. To find the total, you can list the even numbers: 10, 12, 14, ..., 98, which forms an arithmetic sequence where the first term is 10, the last term is 98, and the common difference is 2. The number of terms in this sequence can be calculated as ((98 - 10) / 2 + 1 = 45).

How many 2 digit even numbers?
There are 45 two-digit even numbers. The smallest two-digit even number is 10, and the largest is 98. The two-digit even numbers can be expressed as the sequence 10, 12, 14, ..., 98, which forms an arithmetic sequence with a common difference of 2. The count can be calculated by the formula for the number of terms in an arithmetic sequence.
What is the number of 2 digit even numbers?

How many three digit or four digit even numbers can be formed from the set (23567)?
To form three-digit even numbers from the set {2, 3, 5, 6, 7}, we can use the digits 2 or 6 as the last digit (to ensure the number is even). For each case, we can choose the first two digits from the remaining four digits. For three-digit numbers, there are 2 options for the last digit and (4 \times 3 = 12) combinations for the first two digits, resulting in (2 \times 12 = 24) even numbers. For four-digit even numbers, we again have 2 options for the last digit. The first three digits can be selected from the remaining four digits, giving us (4 \times 3 \times 2 = 24) combinations for each last digit. Thus, there are (2 \times 24 = 48) even four-digit numbers. In total, there are (24 + 48 = 72) three-digit and four-digit even numbers that can be formed from the set.
