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.

we have been given a7 that means 7th term is 3
so plug n=7, d=-2 and a_n=3 into above formula




Hence final answer is c. 15

|a| = a for a ≥ 0
|a| = -a for a < 0
|x| = 74 ⇒ x = 74 or x = -74
check:
|-74|=-(-74) = 74
|74| = 74
CORRECT
<h3>Answer: x = -74 or x = 74.</h3>
