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, ...
Tn=4n+16 If you see, it goes like 20, 24,28,..... So, Tn is just equal to 20+(n-1)4, with first term=20, common difference=4
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.
The nth term is given by: t{n} = (-3x⁴ + 30x³ - 105x² + 106x + 388)/4 for n = 1, 2, 3, 4. Alternatively, your teacher may be expecting a much simpler (also valid) solution: Each term is obtained by subtracting 11 from the previous term: t{n+1} = t{n} - 11 Which means that t0 = t1 + 11 = 104 + 11 = 115 → t{n} = 115 - 11x for n = 1, 2, 3, 4 That formula is NOT valid for any other value of n The first formula gives t1 = 104, t2 = 93, t3 = 82, t4 = 71 and gives t5 = 42, continuing with -41, -232, -603, -1244, -2263,... The second formula gives t1 = 104, t2 = 93, t3 = 82, t4 = 71 (the same first 4 terms) but gives t5 = 60 and continues with 49, 38, 27, 16, 5, ...
Arithmetic sequences are used by people in everyday life for things like planning a budget or making a plan to pay off a mortgage or college loan. They can also be used for simple things such as keeping your daily schedule straight.

7 - 4n where n denotes the nth term and n starting with 0
Tn=4n+16 If you see, it goes like 20, 24,28,..... So, Tn is just equal to 20+(n-1)4, with first term=20, common difference=4
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.

There is no simple answer because there is no simple rule for primes: it is certainly NOT an arithmetic progression.
