Find the next three terms in the sequence 625, 250, 100, 40...

pentagon [3]

Hi!

To solve this, let's divide

625/250 = 2.5

So is the pattern.. x/2.5 = x2/2.5 = x3/2.5...

We can test this theory by multiplying

100 x 2.5 = 250

Since 250 comes before 100 in the sequence then our theory is correct!

So to find the next numbers, divide:

40/2.5 = 16
16/2.5 = 6.4
6.4 = 2.56

The answer is C.

Hope this helps! :)

A withdrawal of $50 is negative or positive?

A withdrawal of $50 is negative because you are taking money out of your account and your money in your account is getting less than what it was before.
