If the formula for additional terms was the summation of the term before it, the nth term of the series would be the sum of all terms prior. In other words it would be the summation of a through n minus 1.
We don't see a question like that very often at all. You've said "the following ..." twice in your question. "The following ... " means "I'm about to show you the item". In your question, there are supposed to be both a list of choices AND an arithmetic sequence "following" the question, but neither one is there. We don't stand a chance!
If you want to ask questions about the "following", then I suggest that you make sure that there is something that is following.If you want to ask questions about the "following", then I suggest that you make sure that there is something that is following.
The one which says: tn = t(n-1) - 4, t0 = 7 or tn = 7 - 4n (for n ≥ 0).
7 - 4n where n denotes the nth term and n starting with 0
There is no simple answer because the position of the missing number is not known. Furthermore, it is not clear whether the sequence is an arithmetic, geometric or some other sequence.
Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...

The explicit formula for an arithmetic sequence is given by an = a1 + (n-1)d, where a1 is the first term and d is the common difference. In this case, the first term a1 is 16, and the common difference d is 4. Therefore, the explicit formula for the arithmetic sequence is an = 16 + 4(n-1) = 4n + 12.

A complex formula in Excel could have many arithmetic operators in it. There are many things that make a formula complex, so a formula with just one arithmetic operator or even no arithmentic operators could be complex too, depending on what it does.
First, count how much is between each number in the sequence. That is the number you will put in front of the x. 4,5,6,7,8... y=1x+b Secondly, solve for b. In this case x=1 then b must be 3 to make it work.
If one may choose the break points, it looks like simple doubling: 3 - 6 - 12 - 24
