The numbers of a sequence are called terms where the th term of a sequence is denoted by the symbol .
Arithmetic sequences are defined by the following equation:
, where is constant.
To find the terms of an arithmetic sequence, the following equation is used:
Where is the th term
is the first term
is the common difference
Find the 10th term of the following arithmetic sequence
Given that and , the 10th term is -21.
If the first three terms of an arithmetic sequence are 11,19 and 27, which term is equal to 115?
Use the rule for the arithmetic sequence:
Now that the rule has been simplified, to find the term equal to 115, substitute the value of into the equation.
