Answer:
Final answer is c. 15
Step-by-step explanation:
We need to find about what is the first term in the sequence for which d = -2 and a7 = 3
We will use nth term formula of arithmetic sequence.
![a_n=a+\left(n-1\right)d](https://tex.z-dn.net/?f=a_n%3Da%2B%5Cleft%28n-1%5Cright%29d)
we have been given a7 that means 7th term is 3
so plug n=7, d=-2 and a_n=3 into above formula
![3=a+\left(7-1\right)(-2)](https://tex.z-dn.net/?f=3%3Da%2B%5Cleft%287-1%5Cright%29%28-2%29)
![3=a+6(-2)](https://tex.z-dn.net/?f=3%3Da%2B6%28-2%29)
![3=a-12](https://tex.z-dn.net/?f=3%3Da-12)
![15=a](https://tex.z-dn.net/?f=15%3Da)
Hence final answer is c. 15
