Answer:
Inequality
Step-by-step explanation:
An <u>inequality</u> is mathematical sentence that compares expression that are not equal.
- <em>Instead of using an equal sign </em><em>=</em><em> , you use an inequality symbol (>, <, ≥, ≤, ≠) with an inequality.</em>
1) 1000 / 100 ⇒ 10 / 1 = 10
1000 ÷ 100 = 10
100 ÷ 100 = 1
2) 9/81 ⇒ 1/9
9 ÷ 9 = 1
81 ÷ 9 = 9
3) 4/64 ⇒ 1/16
4 ÷ 4 = 1
64 ÷ 4 = 16
If you can divide 81 by 4 and end up with a remainder of 1, then yes, 81 is a part of your sequence.
To justify that, it helps to think about ways we can represent numbers in terms of quotients and remainders. For example, if we take 10/3, we’ll obtain the quotient 3 with a remainder of 1, so another way of writing 10 would be 3(3)+1. If we replace that second three with any integer n, 3n+1 represents *every number* that leaves us with a remainder of 1 when we divide it by 3.
By the same logic, 4n+1 represents every number that leaves a remainder of 1 when we divide it by 4. 81 indeed meets this requirement, since can be written as 4(20)+1, so it would be a part of the sequence.
