Answer 1

Based on the given rule, to find your answer you need to plug in the number (term) you which to find.
The first term will be -6 for when you plug 1 for n, the term (1-1) makes the second half of the equation 0 leaving only the -6.
Use the same method for the fourth and tenth term and you will find the answer is the first answer; {-6,-5(2/5),-4(1/5)}
