Add an index column and the custom column to get the next value

Create a blank Query, go to the Advanced Editor, clear the existing code, and paste the codes give below and follow the steps.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMlDSUVIxNDBQitUB8w3BfCM43wjMN4HzjcF8MyA/FgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Year = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Year", Int64.Type}, {"Value", Currency.Type}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 1, 1, Int64.Type),
    #"Added Custom" = Table.AddColumn(#"Added Index", "Custom", each #"Added Index"[Value]{[Index]}?)
in
    #"Added Custom"
