Key Concepts

Geometric Sequence

A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. When applied to depreciation, the remaining value of an asset after each period constitutes a geometric sequence, with the common ratio representing the remaining percentage of value after depreciation for that period.

Depreciation

Depreciation is an accounting method used to allocate the cost of a tangible asset over its useful life. It represents how the value of an asset decreases over time due to wear and tear, aging, or obsolescence, and is important for both financial reporting and tax purposes.

Exponential Decay

Exponential decay refers to a decrease in quantity where the rate of reduction is proportional to the current amount. In the context of depreciation, this means that the asset's value decreases by a consistent percentage each period, leading to a progressively smaller loss in value over time.
