Answer:
I believe the answer is never
Step-by-step explanation:
No, but all real numbers are complex numbers. Complex numbers are numbers consisting of a real number and an imaginary number.
a(n)=1+(n-1)(-3)
Notice there's a common difference of d=-3.
If we use the formula a(n)=a1+(n-1)d to find the nth term given the first term and the common difference, we will see that the function that describes the arithmetic sequence as a(n)=1+(n-1)(-3)
80 is the number in the square root
