Answer:
504
Step-by-step explanation:
I think the correct question is like:The common ratio in a geometric series is 0.50 ( point 5) and the first term is 256.
Find the sum of the first 6 terms in the series.
If it's right, then
Sₙ = (a₁ × (1 - rⁿ)) / (1 - r)
S₆ = (256 × ( 1 - 0.5⁶)) / (1 - 0.5)
= (256 × 0.984375) / 0.5
= 504
hope it will help :)
