Is 54, 48.4, and 46 increasing linear, decreasing linear, increasing non linear or decreasing non linear how do I find the correct answer?

decreasing non-linear

Step-by-step explanation:

The numbers get smaller (the first, 54, is larger than the last, 46), so they are decreasing.

The differences from one number to the next are not the same, so the decrease is non-linear. (The differences are 48.4 - 54 = - 5.6, 46 - 48.4 = - 2.4.)
