2.Hi, i have a task where i need to calculate the 3 months weighted moving average for May 2021, The ...

eight should be based on the count of sales for the previous period, the actual period and the next period. In the excel you can see the housing data: period(month) sum of prices(K) sum of the asses value(T) K/T value (sum of prices/sum of the asses value) The answer i'm looking for is that for May 2021 the price development in percentage should be 9.5% compared to three month back. To calculate the price development you just divide the K/T value, for example: period 1 K/T value = 1.4 period 4 K/T value = 1.9 Price development = (1.9/1.4)-1 = 35.7% increase. So i want to see 9.5% increase on May 2021 compared to 3 months earlier.
