The following list of rows of odd numbers continues in the same pattern:

1) 1

2) 3,5

3) 7,9,11

4) 13,15,17,19
Each row starts where the previous left off, and has one more term than the previous row. There is one row in which the sum of the units digits of the numbers in that row equals .How many terms are in that row?

If I did not misunderstand then,

 

1

 

In the first example the sum of the numbers is 1. There also only is one number in the first example.

Therefore in the first example the sum of all numbers is equal to the amount of numbers.
