Number Patterns

Different Ways of Counting with R

Try the following in R:

• 1:5
• 3:15
• (1:5)*3
• (3:15)*4

By clicking on the links, you should see the same result as you would get from R.
Now, figure out the R code for making the following patterns (also called sequences ):

• 5, 10, 15, 20
• 14, 21, 28, ..., 49
• 12, 15, 18, ..., 300
• 13, 16, 19, ..., 301

Powers

• If you type 3^2, R calculates 3*3: 9.
• If you type 3^4, R calculates 3*3*3*3: 81.

What happens when you try:

• (1:5)^2
• (1:5)^3
• 2^(1:5)
• 3^(1:5)
