deficient
A number whose proper factors add up to less than the number is called deficient. 99 is a deficient number because the sum of its proper factors (1, 3, 9, 11, and 33) is 57.
yes
A perfect number is one with factors (apart from itself) that sum to give the original number. An abundant number is one where this sum is greater than the original number. A deficient number is one where the sum is less than the original number. The factors of 75 are 1, 3, 5, 15 and 25. The sum of these numbers is 49. Thus 75 is a deficient number.
