What is the first term in the sequence for which d = -2 and a7 = 3?
AnnZ [28]

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

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)

3=a+6(-2)

3=a-12

15=a

Hence final answer is c. 15
