weighted moving average

However, the weighted average can be complicated to use if a long time frame is taken.
Additionally, the consumer will most likely want to adjust the weights as time periods pass. That will contribute to the complexity of applying the methods to a wide range of applications, such as predicting inventory item demand.
Hence, the first option is correct
