Find a general term an for the sequence whose first four terms are given.
2, 4, 8, 16, ...
Answer:
an = 2·2^(n-1)
Step-by-step explanation:
There are simple tests to determine whether a sequence is arithmetic or geometric. The test for an arithmetic sequence is to check to see if the differences between terms are the same. Here the differences are 2, 4, 8, so are not the same.
The test for a geometric sequence is to check to see if the ratios of terms are the same. Here, the ratios are ...
4/2 = 2
8/4 = 2
16/8 = 2
These ratios are all the same (they are "common"), so the sequence is geometric.
The general term of a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
Filling in the values for this sequence, we find the general term to be ...
an = 2·2^(n-1)

Please help me. 50 point question
Step-by-step explanation:
Hey there!!!!
Given,
Angle r and angle s are supplementary angle.
And angle r = 120°.
Now, we have,
supplementary angle's sum is always 180°.
So, angle r + angle s = 180°.
or, 120°+ angle s = 180°
Therefore the measure of angle s is 60°.
Hope it helps....

Answer:
for a rectangle to be called a square with 4 sides must be equal
for rectangle to be called a square its four angles must be equal.
Answer:
all parallel sides are the same lengths
all angles are 90°
Step-by-step explanation:
We know that the square has the definition of an object or plane that has all the four sides of equal length,
And all the angles related to the sides are also same. (all angles are 90°)
Whereas, a rectangle gets defined as the plane figure with four straight sides and the same number of right angles where the two parallel sides become of equal length.
what is the answer to -3x+5= -16
Answer: 7
Step-by-step explanation: First you subtract 5 from both sides to single out the -3x. Then you will have -3x = -21. You will then divide both sides by negative three because you want to single out the x. After that, you will have the answer of x = 7
Answer:
x = 7
Step-by-step explanation:
-3x+5=-16
-5 -5
-3x=-21
-3x/3 = -21/-3

2x+8 + 3x+6 = 7x i need help fast
Answer:
x=7 Hope this helps :)
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+8+3x+6=7x
Step 1: Simplify both sides of the equation.
2x+8+3x+6=7x
(2x+3x)+(8+6)=7x(Combine Like Terms)
5x+14=7x
5x+14=7x
Step 2: Subtract 7x from both sides.
5x+14−7x=7x−7x
−2x+14=0
Step 3: Subtract 14 from both sides.
−2x+14−14=0−14
−2x=−14
Step 4: Divide both sides by -2.

Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, what is Stephanie's age?
Answer: Stephanie is 15
Step-by-step explanation:
because you can do 24 divided by 2 which equals 12 then add three to 12 and you get 15.
you're welcome! plz lmk if i'm wrong XD
Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, then Stephanie's age is 15 years.
To find Stephanie's age, we need to follow the given information that her age is 3 years greater than half of her sister's current age.
First, we find half of her sister's age: Half of 24 = 24 / 2 = 12
Next, we add 3 years to half of her sister's age: 12 + 3 = 15
Therefore, Stephanie's age is 15 years.
Age can be used in mathematical equations and word problems to solve for unknowns or to establish relationships between different quantities. For example, age-related math problems might involve scenarios such as Finding someone's age given their birth year and the current year, Calculating the average age of a group of people and Determining the age difference between two individuals based on their birth years.
