Pluto is 5,560,000,000 years old. Estimate the age of Pluto by writing it in the form of x * 10^y years, where x and y are single-digit numbers. 6 * 10^9
6 * 10^8
5 * 10^9
5 * 10^8

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
