A young tree is
16 inches tall. One
year later, it'is 20
inches tall. What is the
percent increase in
height?

25%

Step-by-step explanation:

20-16=4

4/16=1/4

1/4= 25%

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

-6 is the correct option from the above given options
