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.
-3, 12, -48, …
The sequence is multiplying each term by -4 to get the next term.
Therefore, the equation to describe the sequence is:
Tn = -4^n * (-3)
Where Tn represents the nth term in the sequence.
