Three numbers form an AP, if the first and third are 5&245 respectively, find the two possible values

Answer 1

d is the difference between consecutive values in an AP
... there is only one value here
... 5 + d = 245 - d

r is the ratio between consecutive values in a GP
... there would be two possible values
... 5 r = 245 / r

Answer 2

u didnt explain it very well all the way thanks alot

Answer 3

Tracy -- we might take you seriously if you had made your complaint in standard English.

You didn't explain it very well. Thanks a lot.

Answer 4

What Scott did makes perfect sense to me.
Perhaps you will understand it better if we use the standard definitions.

term(1) = a = 5
term(3) = a+2d = 245
so:
5 + 2d = 245
2d = 240
d = 120
So the 3 terms are 5, 125, and 245
There is only one answer, not two like you stated.

If you wanted the 3 terms to be a GP, then follow Scott's steps to get the two possible answers.
