Number Patterns and Recusions
| Question | Answer |
|---|---|
| A sequence is | A list of numbers in a particular order |
| Items in a sequence are called | terms |
| If the term is listed as T10 it is the | tenth term in the sequence |
| Arithmetic sequences | add or subtract a fixed amount from the previous term |
| The common difference is | the amount added or subtracted to an arithmetic sequence |
| The recurrence relation rule is | tn+1 = tn + d |
| To find the nth term of an arithmetic sequence, the rule is | tn= a + (n-1)d |
| The common ratio is | the fixed multiple between terms in a geometric sequence |
| The rule for common ratio is | any term / the previous term |
| Finding the nth term of a geometric sequence | tn= ar^ (n-1) |
