9
The rule that generates the sequence is Un = 9 + 2n (for n = 1, 2, ...
It is an algebraic expression
If you mean 3, 6, 9, 12 then the nth term is 3n
9 < c

The rule that generates the sequence is Un = 9 + 2n (for n = 1, 2, ...
It is an algebraic expression
There are 3 terms in the algebraic expression of: 3y+9+7x
n-squared, or n to the power 2
If you mean 3, 6, 9, 12 then the nth term is 3n
It is two terms of an algebraic expression but if you mean -3 times -9 then it is 27
It is an algebraic expression
It is some kind of an algebraic expression
