Rule to finding terms in a arithmetic sequence?
The nth term of an arithmetic sequence = a + [(n - 1) X d]
What is the diffeence between the term to term rule and the common difference in maths?
The common difference does not tell you the location of the sequence. For example, 3, 6, 9, 12, ... and 1, 4, 7, 10, .., or 1002, 1005, 1008, 1011, ... all have a common difference of 3 but it should be clear that the three sequences are different. A common difference is applicable to arithmetic sequences, not others such as geometric or exponential sequences.
What are the first fourth and tenth terms of the arithmetic sequence described by the given rule A(n) 12 plus (n-1) (3)?
A(1) = 12A(4) = 3 A(10) = -15.
How do you write a rule for the nth term of this arithmetic sequence d equals 4 a14 equals 46?
THIS MAY OR MAY NOT BE CORRECT, but, from what I understand, this is how you do it:it looks like this so far, right?d=4 , a14=46so, using this formula---> an=a1 + d(n-1)plug in your values.now you have: an = a14 + 4(n-1)this is what i think is the answer. for help (better help) with arithmetic sequences, go to:http:/www.basic-mathematics.com/arithmetic-sequence.htmlthis website will really help! there is even an arithmetic sequence calculator!Hope I helped!
What is triangular sequences nth term rule?
