Standard ordinal formation: the numeral '150' plus the productive English ordinal suffix '-th' yields the ordinal meaning.

Etymology

150Th is the number 150 with the small ending -th that turns a number into its place in a line, just like in fourth or fifth. So, 150th means 'in the one hundred fiftieth place' or 'the one hundred fiftieth time'.
