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

The equation of a line is y=-2.5x+3. Which one of these points lies on this line?

lakkis [162]

D is the correct answer. Since this is an equation, equation means both side are equal. So if you put each point in place of y and x and do the math on the left side, the final result of that side has to be equal to the left one. Only (-2,2) follows this statement aka its a point on this line .
