Answer:
Correct choice is A
Step-by-step explanation:
For the numbers 13 and 88, find the difference 88-13:
since 88-13=75 and
(two arithmetic means tells you there will be three intervals), two arithmetic means will be
The only correct sequence is 13, 38, 63, 88.
34% is the correct answer
<u>Answer:</u>
The geometric mean between each pair of numbers 
<u>Solution:</u>
The Geometric mean between two numbers a and b is given as Geometric mean =
--- eqn 1
The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root for the numbers.
From question, given that two numbers are 
Hence we can say “a” =
=7
Similarly “b” =
= 29
We have to find the geometric mean between “7” and “29”
By using equation 1,
Geometric mean between 7 and 29 =
= 14.24
Hence the geometric mean between 
You have to make the denominators(bottom of the fraction) the same in order to combine the fractions.
To make the denominator of
the same as
, you multiply the top and bottom of the fraction by 2 (because they both have a common multiple of 4)

So:

Answer:
1
Step-by-step explanation:
21 = 3*7
65 = 5*13
CGF: to find the greatest common factor, multiply those factors both numbers have in common
GCF :1 since there are no factors in common
