Factor 125 + b^3 completely

( 5  +  b )  ( 25  −  5 b  +  b 2 )

Step-by-step explanation:

 ( a  +  b  )  ( a ^2 −  a b  +  b ^2 )  where  a  =  5  and  b  =  b .

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
