Answer:
- 57
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a + (n - 1)d
where a is the first term and d the common difference
Here a = 13 and d = - 2.5, thus
= 13 + (28 × - 2.5) = 13 - 70 = - 57
Answer:
if this is a fraction, then negative 5 over a⁶
C(x) = 1200(40) + 100
or
= mx+c
where m = 1200, x = 40, y = 100
