Have test tommorow this help more than my teacher thanks!
Thanks man
you are very welcome!
i m bit confused, where to use the formula for a+(n-1)d and ar*(n-1)
the first formula is for arithmetic sequences, second one is for geometric ones
Would not the -1 raised to the power of 7 make positive 1?
Hideyoshi Deluze No, since 7 is an odd number, only exponents raised to an even power always yield a positive number
yes all even powers make the number positive, while negative powers will remain the number negative....
thank you so much!
