the common ratio in geometric series is 0.5 and the first term is 256. what is the sum of the first 6 terms in the series?

501.76

Step-by-step explanation:

common ratio r = 0.5

first term a = 256

sum of G.p = Sn= a( r^n -1)/r-1

sum of the first 6 terms =

S6 = 256( 0.5^6 - 1)/ 0.5 - 1

= 256( 0.0156 - 1)/-0.5

= 256( -0.98)/-0.5

= - 250.88/-0.5

S6 = 501.76

expression #3 is not equivalent. the others are.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
