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

PLEASEEEEEEEEEEEEEEEEEEEEEE Edgar rolls two six-sided number cubes. What is the probability that he rolls a 2 on

<h3>Answer: Choice C</h3>

4/36 = 1/9

==============================================================

Explanation:

Circle the second row. This is where each of the red die results are "2"

Then look at the cases when the second die is less than "5". So we could have a 1, 2, 3, or 4 on this second die.

As you can see, there are 4 cases when the first number is a 2 (red) and the second number is less than 5 (white).

We have m = 4 cases we want out of n = 6*6 = 36 cases total.

m/n = 4/36 = 1/9 is our final answer.
