Need help the input: 3 output:9 input:5 output:25 input:2 output: blank input:7 output:49 input:blank output:64 can you please find the rule.
3 -> 9
5 -> 25
2 -> ?
7 -> 49
if x is input and y is output, it sure looks like
y = x^2
Input: -3 Output: blank
Input: -2 Output: -4
Input: -1 Output: blank
Input: 0 Output: blank
Input: 1 Output: -1
It's difficult to determine the rule with just five examples, but it is possible that the rule is y = -x^2, where y is the output and x is the input.
Input: -3, Output: blank
Input: -2, Output: -4 (since (-2)^2 = 4, and then multiply by -1 for negative results)
Input: -1, Output: blank
Input: 0, Output: blank
Input: 1, Output: -1 (since 1^2 = 1, then multiply by -1 for negative results)
To find the rule in this sequence of inputs and outputs, let's analyze the pattern:
Input: Output
3 : 9
5 : 25
2 : Blank
7 : 49
Blank : 64
Looking at the first two sets, we can observe that the output is obtained by squaring the input number.
3^2 = 9
5^2 = 25
However, there is an inconsistency with the third set, as it states "blank" for the output of 2.
Moving forward, the fourth set seems to follow the same pattern as the first two:
7^2 = 49
Finally, in the fifth set, the input is stated as "blank," and the output is given as 64. Since the previous pattern suggests squaring the input, we can assume that the missing input is the square root of 64, which is 8.
8^2 = 64
Therefore, based on the available information, the rule for this sequence appears to be "Square the input number" except for the third set, where the output is not provided.
