The lcd of two fractions is always greater than the denominator of the fractions. Reasonable or not?

Lcd means least common denomenators
it is normally used to combine fractions with differnt denomenators

I can show 2 disproofs

so
they can be equal
conside
3/4 and 5/8
lcd is 8, 8>8 is false
not reasnable

they can be less if they arenot simplified
example
4/8 and 24/16
lcd is 4

not reasonable

It is not reasonable.
The LCD can be less than the denominators if the fractions are not in simplest form but the LCD can be equal to one of the fractions even if they are in simplest form, for example:
3/4 and 1/2

Hope this helps :)

use the method of successive differences to determine the next term in the sequence: 4, 14, 82, 268, 657, 1359

IRISSAK [1]

The method of successive differences uses subtraction to the one number to the next and the process goes on until the difference settles constant which is not equal to zero. In this case, the constant difference reaches 25. Reversing the process to get the next term, the answer is 2509.
