G 6. Mr. Lesher is painting his kitchen. He used 1 1/8 gallons so far. He bought 3 1/2 gallons. How much does he have left?

Step-by-step explanation:

Calculate 1/8 = 0.125

1 1/8 is 1 + 0.125 = 1.125

Calculate 1/2 = 0.5

3 1/2 is 3 + 0.5 = 3.5

3.5 - 1.125 = 2.375

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
