The graph of which function is decreasing over the interval (-4, oo)? O f(x) = (x + 4)2 + 4 Of(x) = -(x + 4)2 + 4 Of(x) = (x-4)2 - 4 Of(x) = -(x-4)2-4 ​

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
