using the slope intercept formula, y=mx+b where m is the slope and b is the y-intercept, you can substitute the two values to get y=x+5/2. Please note that the slope, m, is one so it's not shown.

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
