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.
