2. Although, technically, the coefficient, 5, is also a constant.
An algebraic letter. e/g 5a 'a' is a non numeric constant. Remember in algebraic , when a letter is given , it means that the value of the letter is a constant, but the value is unknown .
In an arithmetic sequence, the difference between any term and the previous term is a constant.
It is the 2.
a, whatever the value is, would be the constant.

An algebraic letter. e/g 5a 'a' is a non numeric constant. Remember in algebraic , when a letter is given , it means that the value of the letter is a constant, but the value is unknown .
2a + 3a = 5a
Take your pick: a, 2a, 3a, 4a .... etc
The GCF is 5a.
5a times 5a would equal 25a^2.
5a = a + a + a + a + a
It is a constant.
