Junior aims to run a total of 12 miles in 3 weeks. He ran 4 ⅓ miles in the first week and 3 ⅖ miles in the second week. How many more miles would he need to complete to reach his target?

4 miles 4/15

Step-by-step explanation:

4 1/3 + 3 2/5 =

4 5/15 + 3 6/15 =

7 11/15 - 12 =

= 4 4/15

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
