Answer:
29107
Step-by-step explanation:
Every next 'level', a ring of balls is added.
The ring has 6 sides of n balls, but you would then count all 6 corners double, so you have to subtract 6.
So Bₙ = Bₙ₋₁ + 6n - 6
This gives you a sequence of 1, 7, 19, 37, 61, 91, 127, 169, 217, 271, 331, ...
All the way up to 29107 at 100 balls.
Answer:
Step-by-step explanation:
<u>Similar figures have same ratio of corresponding sides:</u>
<u>Substitute:</u>
- 4 / 8 = 7.5 / 3(x - 1)
- 3(x - 1) = 2*7.5
- x - 1 = 5
- x = 6
The answer is 28y because 7y x 4 is 28y
