C is the midpoint of AD. B is the midpoint of AC. BC = 12. What is the length of AD
2 answers:
Answer:
AD = 48
Step-by-step explanation:
C is the midpoint of AD. B is the midpoint of AC. BC = 12.
Let's draw the line segment using the given information.
BC = 12
C is the midpoint AD so C divides the line segment AD into two halves.
B is the midpoint of AC so B divided the line segment AC into two halves.
So, AB = BC
AB = 12
Now let's find AC.
AC = AB + BC
AC = 12 + 12
AC = 24
AD = AC + CD
C divides AD into two halves. So AC = CD = 24
Therefore, AD = AC + CD
AD = 24 + 24
AD = 48

You would use the formula for the specific term you wish to find;
The formula is:
a = starting value of the sequence
d = the common difference (i.e. the difference between any two consecutive terms of the sequence)
n = the value corresponding to the position of the desired term in the sequence (i.e. 1 is the first term, 2 is the second, etc.)
Un = the actual vaue of the the term
For example, if we have the arithmetic sequence:
2, 6, 10, 14, ...
And let's say we want to find the 62nd term;
Then:
a = 2
d = 4
(i.e. 6 - 2 = 4, 10 - 6 = 4, 14 - 10 = 4;
You should always get the same number no matter which two terms you find the difference between so long as they are both consecutive [next to each other], otherwise you are not dealing with an arithmetic sequence)
n = 62
And so:
