Frage 109

A sequence falls by the same amount each time and begins 6, 4, 2, 0. Select all statements that are true about the terms that follow 0.

  1. The term straight after 0 is -2.Richtige Antwort
  2. The term after that one is -4.Richtige Antwort
  3. The sequence stops at 0, because a falling count cannot pass below zero.
  4. The next two terms are 2 and 4, because the values turn back upwards once zero is reached.

Erklärung

The step of two downwards is applied in the same way at every stage, and nothing about zero alters it, so the count carries on to two below zero and then to four below zero. Zero is an ordinary marker on the line rather than a floor, and turning back upwards would mean the step reverses itself with no instruction to do so.
