A quadratic sequence is a sequence of numbers in which the difference between consecutive terms changes at a constant rate. To identify the rule, first calculate the first differences (the differences between consecutive terms) and then the second differences (the differences of the first differences). If the second differences are constant, the sequence is quadratic. The general form of a quadratic sequence can be expressed as ( an^2 + bn + c ), where ( n ) is the term number, and ( a ), ( b ), and ( c ) are constants.
yes
See related link below for a very good explanation
You just have to follow the rule of quadratic functions. Example y = mx+b is the rule for linear functions. ax^2+bx+c is the rule of quadratic equation.
It is no more or n less significant than many other sequences.

No. It is a sequence for which the rule is a quadratic expression.

There is no single rule. Furthermore, some rules can be extremely complicated.

94 and you skip it by 8's
nevermind i got it!!
Oh honey, a quadratic function is a function whose rule is a polynomial of degree 2. It's like the middle child of polynomials - not too simple, not too complex, just right. So next time you see that squared term, you know you're dealing with a quadratic function, sweetie.
The first step is to find the sequence rule. The sequence could be arithmetic. quadratic, geometric, recursively defined or any one of many special sequences. The sequence rule will give you the value of the nth term in terms of its position, n. Then simply substitute the next value of n in the rule.
A polynomial of degree 2.
