I have a range such as: 1780-25-1900-45-2050-65-2550-80.... Now I want an Excel formula so that addition from the range will be: 1780+0 in one cell, 1780+25 in next cell, 1780+25+25 in next cell, 1780+25+25+25 in next cell,..... until it reaches 1900, then 1900+0, 1900+45, 1900+45+45, until it reaches 2050......
