Answer:
sequence is not arithmetic
Step-by-step explanation:
Given:
8,5, 3, 2,
above is not arithmetic sequence
As there is constant difference in consecutive terms in a an arithmetic sequence given by:
d=an- an-1
where
d is common difference
an=nth term
an-1=nth - 1 term
Given sequence
8,5, 3, 2,
d=5-8 = -3
d-3-5=-2
as the difference is not common above sequence is not arithmetic!
Answer:
$120
Step-by-step explanation:
They have raised $780 and need to raise $900.

The answer to your question is B
Answer:
f(-2) = 1
Step-by-step explanation:
f(x) = x^2 + 2x + 1
To find the value f(-2), replace x with -2 and evaluate the expression.
f(-2) = (-2)^2 + 2(-2) + 1
f(-2) = 4 - 4 + 1
f(-2) = 1
