You're looking for a number <em>w</em> such that the numbers
{1 + <em>w</em>, 7 + <em>w</em>, 15 + <em>w</em>}
form a geometric sequence, which in turn means there is a constant <em>r</em> for which
7 + <em>w</em> = <em>r</em> (1 + <em>w</em>)
15 + <em>w</em> = <em>r</em> (7 + <em>w</em>)
Solving for <em>r</em>, we get
<em>r</em> = (7 + <em>w</em>) / (1 + <em>w</em>) = (15 + <em>w</em>) / (7 + <em>w</em>)
Solve this for <em>w</em> :
(7 + <em>w</em>)² = (15 + <em>w</em>) (1 + <em>w</em>)
49 + 14<em>w</em> + <em>w</em> ² = 15 + 16<em>w</em> + <em>w</em> ²
2<em>w</em> = 34
<em>w</em> = 17
Then the three terms in the sequence are
{18, 24, 32}
and indeed we have 24/18 = 4/3 and 32/24 = 4/3.

Please, please give brainliest, it would be greatly appreciated, I only a few more before I advance, thanks!
This is basically a system of 3 linear equations with variables x, y and c.
x+y = 6...................................(1)
5x/3 + y = c .........................(2)
2y = c-4x .............................(3)
(2)-(1)
5x/3-x +y-y = c-6 => 2x/3 = c-6 => x = (3/2)(c-6)=3c/2-9 ..............(4)
(3) - 2(2)
2y-2y - 10x/3 = c -4x -2c
=> 2x/3 = -c
=> x = -(3/2)c.............................................................................................(5)
Finally, equate (4) & (5) to get
3c/2-9 = -3c/2
=>
3c = 9
=> c=3
