ANSWER THIS QUESTION CORRECTLY.
Write an equation to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term.
-0.42, 2.1, -10.5, …
The given sequence alternates between two terms: -0.42 and 2.1.
For odd values of n, the term is -0.42, and for even values of n, the term is 2.1.
Therefore, the equation to describe the sequence is:
(-1)^(n+1) * 0.42 * n
