Answer:
D) An = -5n +12; -58
Step-by-step explanation:
The given sequence An = {7, 2, -3, -8, -13}
First terms Ao = 7
It is an arithmetic sequence.
D = 2 - 7
D = -5
Explicit formula An = A0 + (n - 1) d
= 7 + (n-1)(-5)
= 7 -5n + 5
An = -5n + 12
Now let's find A14
A14 = -5(14) + 12
= -70 +12
= -58
Answer: D) An = -5n +12; -58
Thank you.
