The disparity between trillion and the final two numbers, quadrillion and quintillion, in fact, is so great that they barely register on the bar graph. Those numbers, in ascending order, are sextillion, septillion, octillion, nonillion, and decillion.
Also question is, what comes after a trillion and so on?
It goes million, billion, trillion, quadrillion, quintillion, sextillion, septillion, octillion, nonillion, and decillion.
What comes after one zillion?
No such thing as a zillion - but what's after a trillion? After a trillion comes a trillion and one, and so on and so forth, until you get to a quadrillion, which has 15 zeros. Then is a quintillion, 18 zeros; a sextillion, 21 zeros; and on up to a centillion, which has 303 zeros.
