PLS HELP FAST! Write the first four terms of a decreasing Arithmetic Sequence. Use this to describe, in your own words, how to write both the Recursive and the Explicit Formulas for the sequence. Show how to use the
Recursive Formula to find the next two terms

Write the first five terms of the sequence defined by the recursive formula.

The first term is given in the formula. For each subsequent term, we replace \displaystyle {a}_{n - 1}an−1 with the value of the preceding term.
