Question

answer the question correctly to continue: which number belongs in the set of integers but not whole numbers? -2 0 3.5 5

Explanation:

Step1: Recall number - set definitions

Integers include positive and negative whole numbers and zero ($\cdots, - 2,-1,0,1,2,\cdots$). Whole numbers are non - negative integers ($0,1,2,\cdots$).

Step2: Analyze each option

• Option $- 2$: It is an integer ($\cdots,-2,-1,0,1,2,\cdots$) and not a whole number since whole numbers are non - negative.
• Option $0$: It is an integer and also a whole number.
• Option $3.5$: It is a decimal number and not an integer.
• Option $5$: It is an integer and also a whole number.

Answer:

$-2$
