The answer depends on the type of grass you're planting. Cool-season grasses grow best when temperatures are between 60-80 degrees. Early fall is the best time to seed because of its shorter days, cooler nights, and heavier dews.
The definition of odd is given by 2n+1, where n is an integer. So if n=0: 2(0)+1 = 0 + 1 = 1 When n is 0, you get the first smallest positive integer, therefore when n is 45 you'd actually get the 46th smallest positive real integer. Therefore, the 45th smallest positive odd number is given by: 2(45-1)+1 = 2(44)+1 = 88 + 1 = 89 Note: the -1 represents offsetting the numbers, because we begin counting at zero. The answer is 89.

About Positive and Negative Numbers. Positive numbers are any numbers greater than zero, for example: 1, 2.9, 3.14159, 40000, and 0.0005. For each positive number, there is a negative number that is its opposite. We write the opposite of a positive number with a negative or minus sign in front of the number, and call these numbers negative numbers. The opposites of the numbers in the list above would be: -1, -2.9, -3.14159, -40000, and -0.0005.
