Abattery was charged. when the charging began, it was 23 percent full. after 30 minutes of charging, the battery was 89 percent full. how fast did the battery charged? percent per minute how long did it take the battery to be fully charged? minutes

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
