Let P(n) be "a postage of n cents can be formed using 5-cent and 17-cent stamps if n is greater than 63".Basis step: P(64) is true since 64 cents postage can be formed with one 5-cent and one 17-cent stamp.Inductive step: Assume that P(n) is true, that is, postage of n cents can be formed using 5-cent and 17-cent stamps. We will show how to form postage of n + 1 cents. By the inductive hypothesis postage of n cents can be formed using 5-cent and 17-cent stamps. If this included a 17-cent stamp, replace this 17-cent stamp with two 5-cent stamps to obtain n + 1 cents postage. Otherwise, only 5-cent stamps were used and n 65. Hence there are at least three 5-cent stamps forming n cents. Remove three of these 5-cent stamps and replace them with two 17-cent stamps to obtain n + 1 cents postage.Hence P(n + 1) is true.

People tend to photograph these slides so make sure the information is error free and that you add you own marketing info to the slide as well.

<u>Explanation:</u>
Graphics user interface (gui) made a big resolution on desktop or laptop or tablet or workstation industries. In olden days till 1994 still, people were using the black and white computer where a desktop consists of keyboard and printer and monitors where display color white and black.
If we open a picture it will display only in black and white so games are in black and white mode. After windows 3.1 we have seen color picture and mouse interface is used. Since technology developed and interface in GUI is also developed improved in windows icon menu and mouse pointer.
As technology developed we going back to a dark mode such as black and white mode.
