Given a list of numbers, write a function to determine if the list is an arithmetic sequence. An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. Additionally, the first and last numbers in the list should also be divisible by the common difference.

You are given an array `nums` of integers. Your task is to write a function `checkPossibility(nums)` that modifies the array in one move to make it a non-decreasing array. A non-decreasing array is an array where `nums[i] <= nums[i + 1]` for all `i`. You need to determine if it's possible to make the array non-decreasi... | codefeedback | [
