Write a number that is gratet than 1 in scientific notation explain how you knowit is grater than 1

2 x 10^2 because 2 x 10^2 is 200 in standard form and 200 is greater than 1.

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
