The function (sequence generator) f(x) with x∈ℕ has been defined as a recursive function (sequence), with the initial value defined for some x, ie starting form some some natural number (in this case 1), the value of the function (sequence) is given (in this case f(1) = 1), and each successive value of the function (sequence) is defined in terms of the current value f(x+1) = f{x} + g(x) where g(x) is a function with g(x) = 3x(x + 1).
f(x + 1) = f(x) + 3x(x + 1)
f(1) = 1
→ f(2) = f(1 + 1) = f(1) + (3×1)(1 + 1) = 1 + 3×2 = 1 + 6 = 7
→ f(3) = f(2 + 1) = f(2) + (3×2)(2 + 1) = 7 + 6×3 = 7 + 18 = 25
I'll let you evaluate the rest.
Hint:
f(4) = f(3 + 1) = f(3) + (3×3)(3 + 1)
f(5) = f(4 + 1) = f(4) + ...
f(6) = f(5 + 1) = f(5) + ...
No. The set of binary numbers includes fractions which are written in binary form. For example, binary(0.1) = decimal(0.5) which is not a natural number.
No, a set of natural numbers is not a group under the operation of addition. For a set to be a group, it must satisfy four properties: closure, associativity, identity, and inverses. While the natural numbers are closed under addition and associative, there is no additive identity (0 is not included in the natural numbers) and no inverses (there is no natural number that can be added to another natural number to yield zero).
what are the seven properties of rational numbers
If at least one of the numbers is even, the result will be even. Otherwise all the numbers are odd and the result will be odd.
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
The Count function can be used if you are looking for just numbers and the Counta function if you are looking for numbers and text entries.
the atomic masses and atomic numbers... group number and period number... valence electrons and number of shells... these all determine the chemical properties of elements...
A sequence is a function ! whose domian is the set of natural numbers
Integers are a set of numbers including natural numbers (1, 2, 3...) their opposites (-1, -2, -3...) and 0.
No. The set of binary numbers includes fractions which are written in binary form. For example, binary(0.1) = decimal(0.5) which is not a natural number.

You do not need a function to determine the lowest common factor of two numbers. The lowest factor of any one number is 1. The lowest common factor of any two numbers is therefore 1 as well.
If at least one of the numbers is even, the result will be even. Otherwise all the numbers are odd and the result will be odd.
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
It is the set of natural numbers.
