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
I believe the X numbers are divided by 2, to get the Y numbers. So the blank X box is 1 and the other is 12.
2+2=4 because 1+1+1+1 equals and those 2 problems are the same. You got to at least know 1+1+1+1.!
