How do you write an expression
No. It is a sequence for which the rule is a quadratic expression.
To write in terms of ( n ), you express a variable or equation using ( n ) as a reference point or variable. This often involves substituting ( n ) into an existing expression or defining a relationship where ( n ) represents a specific quantity, such as a sequence index or a parameter. For example, if you have a sequence defined as ( a_n = 2n + 3 ), you're expressing the terms of the sequence directly in terms of ( n ).
sequence
the same : expression
A sequence is just an ordered set of events. You write it by telling what happened in order.
You can always write a numerical division expression as a decimal.
cat is under the table
write something, leave a space, write something else.
Except in very basic cases you cannot. Any table can be converted to a sequence of numbers, which might include gaps. Then following from Wittgenstein's Finite Rule Paradox every finite sequence of numbers can be a described in infinitely many ways and so there are infinitely many possible relationships - some simple, some complicated but all equally valid.
You write it exactly as in the question.
