Frans fudge recipe calls for 2 1/2 cups of sugar and she increases it by 2/5 of a cup, how much sugar does she use?

3.46 cups

Step-by-step explanation: multiply the number of cups she uses (2 1/2) by 2/5 or .4.. that gives you 0.94.. then add the 0.94 back to the original 2 1/2 to get the total amount of sugar

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
