12,60,-300,1500 what are the next two number s

- 7500, 37500

Step-by-step explanation:

Note the common ratio r between consecutive terms of the sequence, that is

r = 60 ÷ - 12 = - 300 ÷ 60 = 1500 ÷ - 300 = - 5

This indicates that the sequence is geometric with r = - 5

To obtain the next term in the sequence multiply the previous term by - 5

1500 × - 5 = - 7500

- 7500 × - 5 = 37500

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
