Answer:
x=27
Step-by-step explanation:
The mean is add all the numbers and divide by the number of points
(2+7+x)/3 =12
Multiply each side by 3
(2+7+x)/3 *3 =12*3
2+7+x = 36
Combine like terms
9+x = 36
Subtract 9 from each side
9+x-9 = 36-9
x = 27
Note that
n^m*n^r=n^(m+r)
2^5*2^x=2^(5+x)
the answer is D
Let w represent the amount the wife receives.
.. w +2*(2/3*w) = 945,000
.. 7/3w = 945,000
.. w = (3/7)*945,000 = 405,000
The wife will receive $405,000.
Let the n-th term be called

We see that if we choose

then the other numbers follow the pattern

(see :

)
Hence the sequence will be
