Sixteen blocks of the same material are arranged in a line, the difference in masses between any block and its preceding one being constant. When the same quantity of heat is supplied to the first and the last block, the rise in temperatures is found to be in the ratio 1 : 2. Find the ratio of the masses of the first and the eleventh block.
