Answer:
66
Step-by-step explanation:
90-24=66
Let
be the constant factor between terms, so that


and so on, with

(notice how the exponent and the subscript add to
)
Then

so if

then

Now,

so the third term in the sequence is 30.
First, let's convert 0.77 to a fraction.

Multiply by 100

Now make the denominators the same, to make it easier to find which fraction is greater. We can do this by finding the LCM of the denominators, then however many times the denominator goes into that number, we multiply the numerator by the same amount.
For example, the LCM of 100 and 6, is 300. 6 goes into 300 50 times, so the numerator for 4/6 is 200 (4 x 50 = 200). :)

The answer is 0.77 is greater than 4/6. :)
