Write the explicit formula for the geometric sequence.
a1 = −5, a2 = 15, a3 = −45

Step-by-step explanation:

A geometric sequence or progession is defined as a sequence where each term can be found by multiplying a factor with the first term.

In this case, the first term is -5, the second term is 15 and the third term is -45.

To find the factor, we divide the second term by the first, and the third term by the second.

As you can notice, the factor is -3, so .

Now, the explicit formula of this sequence can be found with

Where refers to the n-th term.

Replacing values, we have

Therefore, the explicit formula of the geometric sequence is

Which can be used to find any other term in the sequence.

step-by-step explanation:

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.
