Answer: $False$

The answer to this problem is $n=-3$

To get -3 here is the work shown

Simplify both sides of the equation

$n-12=-15$

Add 12 to both sides

$n-12+12=-15+12\\n=-3$

Determine 4th term in the geometric sequence whose first term is -2 and whose common ration is -5.

anygoal [31]

Answer:

$a_{4}$ = 250

Step-by-step explanation:

To obtain any term in the geometric sequence multiply the previous term by the common ratio r

here r = - 5 and $a_{1}$ = - 2, hence

$a_{2}$ = - 2 × - 5 = 10

$a_{3}$ = 10 × - 5 = - 50

$a_{4}$ = - 50 × - 5 = 250

riadik2000 [5.3K]

Answer: for 2 cups, There are 232 Calories.

Step-by-step explanation:

Step 1

Let the calories in one cup be represented as C

Therefore

3/4 x C = 87 calories

C = 87 X 4 / 3 = 116

unit rate is 116 calories per cup.

Step 2- Solving the number of calories in 2 cups

1 cup serving = 116 calories

2 cups servings = 116 x 2= 232 calories
