Hello :
the nth term ( general term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d , A1 : the first terme
A1 = 5 and : d = 1 - 5 = - 4 n = 21
A21 = 5 + (21 -1)(-4)
A21 = 5 - 80 = -75

f(2)=-2 is the answer
Answer:
15*C
Step-by-step explanation:
The temperature rises by 2.4 every 3 cycles per second. So you would have to keep the pattern going.

0 cycles p/second = 15.0*C
So, because 0 cycles means the engine is resting, 15*C would be the answer.
there is no table to get our answers off of.
