Let the numbers be x and y; x being the larger number and y being the smaller.
Given,
x + y = 2* (x - y)
x + y = 2x - 2y
x = 3y
Also given,
x = 6 + 2y
3y = 6 + 2y
--- y = 6
Thus, x = 3y = 3*6 = 18.
Therefore, the numbers are 18 and 6.
Answer :
Let the first term of both the terms be
and last term be 
Now, by using the mid point formula to find the mid point of the segment -

Now, by substituting the values of both x and y -

Adding -7 and 6 -

Now, move the negative in front of the fraction -

The answer is c) 45 times PI cubed.
a rough estimate is 26 because 20+2(3)=26
3 pounds of apples are 6.36

Answer: 1) 2, 3, 4, 9, 32, 279, 8896, 2481705, 22077238784
2) 2,490,924
3) Neither
<u>Step-by-step explanation:</u>


Neither
Not arithmetic because the difference between each of the terms is not the same.
S₂ - S₁ S₃ - S₂ S₄ - S₃
3 - 2 = 1 4 - 3 = 1 9 - 4 = 5
Not geometric because the ratios between each of the terms is not the same.
