Answer:
The formula given for finding the sum of whole numbers from 1 to any whole number [tex]\( n \)[/tex] is:
[tex]\[\frac{n(n + 1)}{2}\][/tex]
Using this formula, we can find the sum of whole numbers from 1 to 10 by substituting [tex]\( n = 10 \)[/tex]:
[tex]\[\frac{10(10 + 1)}{2} = \frac{10 \times 11}{2} = \frac{110}{2} = 55\][/tex]
So, the sum of the whole numbers from 1 to 10 is 55. The correct answer is A) 55.
