To count backward from the given numbers, you should organize them in descending order. Let's break down the sequence step by step:
The original list of numbers given is:
115
132
164
198
277
351
243
465
Let's now rearrange these numbers in descending order to count backward:
465
351
277
243
198
164
132
115
By listing the numbers in this order, we have successfully counted backward from the largest to the smallest. Each step simply involves identifying the next largest number from those remaining and listing it until all numbers are arranged.
