The punch bowl at Felicias party is getting low, so she adds 12 cups of punch. The punch bowl now contains 11.5 cups of punch. How many cups of punch were in the punch bowl before Felicia refilled it

Initial cups = -0.5 cups of punch

Step-by-step explanation:

Added cups of punch = 12

Final cups of punch = 11.5

The initial cups of punch before it was refilled = final cups - added cups

Initial cups = 11.5 - 12

Initial cups = -0.5

what the question so we can you out

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
