4
Fibanocci numbers are each the sum of the 2 previous numbers, i.e. 1,1,2,3,5,8
Thus 4 is the first one missing
By modern definition, the above response is incorrect - 0 (zero) is both positive (it is defined as such) and not in the Fibonacci set. This answer is given based on a slight assumption, there cannot be a "first number" on a number line. The lowest number that is positive and not within the set of Fibonacci numbers (as inferred as the true meaning of your question) is zero.
1 is the first positive number on the number line.
no, If the original number is positive, it adds the absolute value (always a positive) to the first number thus doubling it
You can do this by inspection. If the second number is smaller than the first, their difference is positive. If the second number is greater than the first, then their difference is negative. If the second number is the same as the first number, then their difference is zero.
4
Not necessarily. A negative number plus a positive number can be negative, zero or positive.
4
no not always. as long as the first number is bigger than the second number. if it is not, the answer is negative. 7-5=2 5-7= -2
Yes. to subtract a negative is to add that number, so the number will be higher than the first number which is positive and can't go below zero.
a negative number minus a negative number is a negative number plus a negative number the answer depends on the value of the first number if the first number's absolute value is larger than the second number's absolute value than the answer is negative if the first number's absolute value is less than the second number's absolute value than the answer is positive
Since zero is both a positive number (defined as such), and not part of the Fibonacci sequence, then the first positive non-Fibonacci number is zero (0). If zero does not fit in you definition of positive number, then the answer would be four (4).
1 is the first positive number on the number line.
Larger.
Negative first, then zero and then the positive.
(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number
no, If the original number is positive, it adds the absolute value (always a positive) to the first number thus doubling it
No. As both negative and positive numbers can be odd, there is no first odd number, and therefore no 100th odd number. The 100th odd positive number is 199.
Subtract one number from the other. If the answer is a positive number then the first number is greater than the second number. If the answer is a negative number then the second number is greater than the first number. 9.5 - 4.6 = 4.9 (a positive number so 9.5 is greater than 4.6)
