lol

SuperMan

Jul 19, 2016 14:52

The given answers are strange

SuperMan

Jul 19, 2016 14:49

yeah

SuperMan

Jul 19, 2016 14:48

But that is hard when you can't solve it even at 50%

SuperMan

Okay, thanks!

SuperMan

Have to find those 4 numbers

SuperMan

Jul 19, 2016 14:43

Here is the short condition:
The logarithms of 4 positive numbers with base 2 make an arithmetic progression. The multiplication of it's first and last members is = -8 and the multiplication of the middle ones is = 0

SuperMan

Jul 19, 2016 14:39

Hellol, can we talk here?

SuperMan

Jul 19, 2016 14:39

Thank you very much!!! I appreciate it! Could I ask about another progression?

SuperMan

Jul 19, 2016 14:39

I saw it and solved the task! Thank you again! Got question about arithemtic progression and logarithm, should I make a new post?

SuperMan

Jul 19, 2016 14:39

Thank you! Any ideas how to find a and q? :)
