What is the sum of the geometric sequence -4 24 -144 if there are 8 terms -959,781 29,637 26,661 959,780

The correct answer is 959,780.

In order to find this, we need to first find all the first 8 terms of the series. Each term is the previous term multiplied by -6. This gives us the following terms.

-4

-4*-6 = 24

24*-6 = -144

-144*-6 = 864

864*-6 = -5,184

-5,184*-6 = 31,104

31,104*-6 = -186,624

-186,624*-6 = 1,119,744

Now we add all those together and get our answer.

-4 + 24 - 144 + 864 - 5,184 + 31,104 - 186,624 + 1,119,744 = 959,780

right

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
