In the arithmetic sequence 4, 4 1/2, 5, ... what term is 224?
I have got this so far, but not sure if this is correct.
224=4 + (n-1) (1/2)
220=1/2n-1/2
220 1/2 = 1/2n
220=n
correct lol
i would actually think you are wrong. i may not be good at math, but when i figured it out, i got:
224 = 4+( (n-1) * 1/2) => n = 441
may wanna check again..? i dont know, up to you. like i said, not good at math so may be wrong or not.
You have the right idea....just a little faulty execution....take it from here
220 = (n- 1) (1/2) multiply both sides by 2
440 = n - 1 add 1 to both sides
441 = n ...so ...it's the 441st term....just as Guest said....
