The number 49 is an integer that comes after 48 and before 50. It is the square of 7, as \( 7 \times 7 = 49 \). In addition, 49 is an odd number, a composite number (because it has divisors other than 1 and itself), and can be expressed as the sum of six consecutive positive integers: \( 7 + 8 + 9 + 10 + 11 + 12 = 49 \).
