Answer:

<em>x, 2x+1, 4x+3, 8x+7</em>

Step-by-step explanation:

If we call the first term <em>x</em>, then the subsequent term is <em>2x+1</em>. Then, the next term is <em>2(2x+1)+1=4x+2+1=4x+3</em>. Then, the fourth term is <em>2(4x+3)+1=8x+6+1=8x+7</em>.

As a matter of fact, the <em>n</em>th term is given by 2^{n-1}x+2^{n-1}-1 for starting term <em>x</em>.
