The geometric mean of 9 and 25 is: 15.0
The geometric mean of 9 and 81 is 27.0
A geometric sequence is : a•r^n while a quadratic sequence is a• n^2 + b•n + c So the answer is no, unless we are talking about an infinite sequence of zeros which strictly speaking is both a geometric and a quadratic sequence.
To check whether it is an arithmetic sequence, verify whether the difference between two consecutive numbers is always the same.To check whether it is a geometric sequence, verify whether the ratio between two consecutive numbers is always the same.
1/9 + 1/b = c 1/b = c - 1/9 1 = cb - b/9 9 = 9cb - b 9 + b = 9cb (9 + b)/9c = b *parenthesis here means its all over 9c.

well, i think if you use this you can find out. A = 1-9 ,B = 0-9 , C = 0-9 , D = 0-9 , E = 0-9 for 2digit numbers = A A for 3 digit numbers = A B A for 4 digit numbers = A B B A and so on till you get to for 8 digit numbers = A B C D D C B A for 9 digit numbers = A B C D E D C B A and last for 10 digit number = A B C D E E D C B A this should work...

This is the associative law for addition: If a, b, c are any numbers then: a + (b + c) = (a + b) + c
Well, isn't that just a happy little math problem! If A is less than B and B plus C equals 10, then it must be true that A plus C is less than 10. Just remember, in the world of numbers, everything adds up beautifully in the end.

Yes. By the associative property, a + b + c = a + c + b.
