The first term is 5. The sequence goes by 2. And 23 is the 9th term. 9x2=18
23-18=5
What figure is there, nothing is shown. Name?
There is no work to show. It is really just trial and error till you get the hang of it. You look at the multiples of the last term and find.which add or subtract to the middle terms coefficient. Use DeCartes law of signs to determine if it is plus or minus.
1. Does not factor solve using other method
2. (X-5)^2
Alright, 4 to the 8th power is 4x4x4x4x4x4x4x4 which ends up as 65,536.
4 to the 5th power is the same thing but with 5 4's and that is 1,024.
All you need to do now is 65,536/1,024 = 64.
Solved! :D
