I can write an equation to represent an arithmetic sequence.
- 1
Arithmetic sequences are patterns that add or subtract the same number each time, and their points form a straight line when plotted.
- 2
The equation for an arithmetic sequence, t(n) = mn + b, is similar to y = mx + b, where 'm' represents the growth (or slope) and 'b' represents the t of zero term.
- 3
To find the t of zero term (b), calculate the term that comes before the first term in the sequence by using the opposite operation of the growth.
