10 - 4n
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.
Well, darling, it looks like we have a simple arithmetic sequence here. The common difference between each term is 1, so the nth term formula is just n + 3. So, if you want the nth term for 4 5 6 7 8, it's n + 3. Hope that clears things up for ya!
Unless the operands form an arithmetic sequence, it is not at all simple. That means the difference between successive points must be the same. If that is the case and the SECOND difference in the results is constant then you have a quadratic.
Oh, dude, that's just a simple arithmetic sequence with a common difference of -4. So, to find the nth term, you can use the formula a_n = a_1 + (n-1)d, where a_1 is the first term (10), d is the common difference (-4), and n is the term number. Just plug in the values and you'll get your nth term. Easy peasy, lemon squeezy!

7 - 4n where n denotes the nth term and n starting with 0
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!
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.
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.
The one which says: tn = t(n-1) - 4, t0 = 7 or tn = 7 - 4n (for n ≥ 0).
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.
If one may choose the break points, it looks like simple doubling: 3 - 6 - 12 - 24
