Popular Problems. Algebra. Identify the Sequence 0 , 3 , 6 , 9 , 12. 0 0 , 3 3 , 6 6 , 9 9 , 12 12. This is an arithmetic sequence since there is a common difference between each term. In this case, adding 3 3 to the previous term in the sequence gives the next term. In other words, an = a1 +d(n−1) a n = a 1 + d ( n - 1).

Solution - Arithmetic sequences. The common difference equals: 3. The sum of the sequence equals: 18. The explicit formula of this sequence is: a n = 0 + ( n − 1) ⋅ 3. The recursive formula of this sequence is: a n = a ( n − 1) + 3. The nth terms: 0, 3, 6, 9, 12, 15, 18... See steps.
Finding Missing Numbers. To find a missing number, first find a Rule behind the Sequence. Sometimes we can just look at the numbers and see a pattern: Example: 1, 4, 9, 16, ? Answer: they are Squares (1 2 =1, 2 2 =4, 3 2 =9, 4 2 =16, ...) Rule: xn = n2. Sequence: 1, 4, 9, 16, 25, 36, 49, ... Did you see how we wrote that rule using "x" and "n" ?
