Estimate 31,969 divided by 488. round the numbers and the divide.

32000/500= 64 approximately

Step-by-step explanation:

64 is the answer because 31969/488= 65.51

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
