Answer:
an = 2(2)^(n-1)
Step-by-step explanation:
Sorry for the confusion, it would be a geometric sequence an = 2(2)^(n-1).
an = a1(rate of change)^(n-1)
the starting is 2
the rate is multiplying by 2
so it would be an = 2(2)^(n-1)
if you still don't understand let me know in comments.
Answer:
32 slices
Step-by-step explanation:
as each slice is 1/8 of pizza, there are 8 slice on each pizza
as such 4 pizzas will have 4*8=32
To start, you would add 9 plus 8 to find the number of students there are now and that is 17 and 204 divided by 17 equal 12 so you would multiply 9 by 12 and 8 by 12 to get a 108 boys:96 girls ratio an when you add those together you get 204.
