The formula for any arithmetic sequence is an = a1 + d ( n - 1), where an represents the value of the n th term, a1 represents the value of the first term, d represents the common difference, and n represents the term number. what is the formula for the sequence 10, 8, 6, 4,

an = 10 + (-2)( n - 1)
an = 10 + 2( n - 1)
an = -2 + 10( n - 1)
an = 2 + 10( n - 1)

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
