X + 9 = 2x - 8
2x - x = 9 + 8
x = 17
BC = x = 17

Answer:
The explicit form for this sequence is
for all
.
Step-by-step explanation:
The explicit form of an arithmetic sequence of numbers is given by the formula
, where
is the first term of the sequence,
is the difference between two consecutive terms of the sequence, and
.
We know that the first four elements for the arithmetic sequence are
.
To find the general formula for this problem we only need to calculate
in the above formula.
For n=2, we have

if we replace
and
and solve for
we obtain


Therefore the explicit form is
for all
.
