Step 1. Write the given information.

The given sum is:

12+23+34+.....+1313+1

02

Step 2. Write the sum using summation notation.

As we can see that the sum 12+23+34+.....+1313+1has 13 terms, each term represents the form kk+1, and this sum starts at 12and ends at 1313+1.

Therefore,12+23+34+.....+1313+1=鈭�k=113kk+1.
