Answer:
where's the question I'm confused
Answer:
.03x+-1=y becoz the line is crossing at about 0.3 and the y intercept is -1
Check the forward differences of the sequence.
If
, then let
be the sequence of first-order differences of
. That is, for n ≥ 1,

so that
.
Let
be the sequence of differences of
,

and we see that this is a constant sequence,
. In other words,
is an arithmetic sequence with common difference between terms of 2. That is,

and we can solve for
in terms of
:



and so on down to

We solve for
in the same way.

Then



and so on down to


Answer:
C. since 8, 15, 17 are pythagorean triples
