Is there an arithmetic sequence of natural numbers in which no term is a perfect square?
I believe this is one: [(X,... X+1,... X+2,... X+3,...) squared] +1 Where X is any natural number. (X) squared + 1 (X + 1) squared + 1 (X + 2) squared + 1 (X + 3) squared + 1...
What does the mathematical term squared mean?
In mathematics, the term "squared" refers to multiplying a number by itself. For example, if a number x is squared, it is equivalent to x multiplied by x, or x^2. It is a way of indicating that a number is being raised to the power of 2.
Why is x squared called x squared?

What is 3X divided by X squared?
The expression 3X divided by X squared can be simplified by dividing the coefficient of X by the coefficient of X squared. In this case, 3X divided by X squared simplifies to 3/X. This is because when dividing by a term with an exponent, you subtract the exponents in the denominator from the exponents in the numerator.
