1.

A sequence is defined by f1=−3f1=−3, fn=fn−1+0.5fn=fn−1+0.5 for n≥2n≥2. Diego writes an equation for the nth term of the sequence as an=−3+(n−1)(0.5)an=−3+(n−1)(0.5). Is he correct? Explain how you know.

2.
  1. How would you describe the representation f1=−3f1=−3, fn=fn−1+0.5fn=fn−1+0.5 for n≥2n≥2 for Diego’s sequence?

  1. How would you describe the representation of Diego’s sequence, an=−3+(n−1)(0.5)an=−3+(n−1)(0.5)?
