Thanks man

[@brianmclogan]

you are very welcome!

[@muhammadowais-vd2sh]

i m bit confused, where to use the formula for a+(n-1)d and ar*(n-1)

[@FishyRaijin]

the first formula is for arithmetic sequences, second one is for geometric ones

[@courtneycunningham7646]

thank you so much!

[@hideyoshilacan66]

Would not the -1 raised to the power of 7 make positive 1?

[@Seth_Arvila]

Hideyoshi Deluze No, since 7 is an odd number, only exponents raised to an even power always yield a positive number

[@muhammadowais-vd2sh]

yes all even powers make the number positive, while negative powers will remain the number negative....
