How can the mean of the values in a numerical data set be calculated? A
Order the values in the data set from least to greatest, then find the middle value.
B. Find the sum of the values in the data set, then divide by the middle value in the set.
с
Find the sum of the values in the data set, then divide that sum by the number of values in the set
D
Order the numbers in the data set from least to greatest, then subtract the least value from the greatest value.

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
