9. Is -any term of the series 4,-2, 1.....?127

1.	9. Is -any term of the series 4,-2, 1.....?127
Answer» This is a Geometric Progression with common ratio (-1/2). So, a*r^n = 1/127=> r^n = 1/508.=> (-1/2)^n = 508n does not have any integer value for such an equation. So, this term does not exist for the progression. Please hit the like button if this helped you.
