The population of a city is 50,000. It is increasing at an annual rate of 3%. What is the
population of this city in 4 years?

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

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
