50% off means half price, so half of 49.98 is 24.99
the necklace now costs 24.99 dollars
F(n) = 1st term - common difference (n - 1)
The operation is subtraction because the sequence is decreasing.
n = number of the term you are looking for
1st term = 1st number in the sequence, in this case, 16
common difference = difference between one number to the next
f(n) = 16 - 1(n-1)
Assuming we are looking for the 5th term.
f(5) = 16 - 1(5-1)
= 16 - 1(4)
= 16 - 4
= 12 * as you can see, 12 is the 5th term of the sequence.
If you are looking for the equivalent of the nth term, simply substitute n by the number you are looking for and solve the equation.
Y = 2 x + 18 i think thats the answer :D

Answer:
ASA
Step-by-step explanation:
One pair of corresponding angles (in the bottom left/right) are already marked for us, and we're also given a pair of corresponding sides (the 8cm ones on the left and right). The two triangles have one more angle in common too - the one they're overlapping on the top corner. So, we have:
- Two pairs of congruent corresponding angles, and
- A pair of congruent corresponding sides between them,
which is enough information to call the triangles congruent by Angle-Side-Angle (ASA).
