Step-by-step explanation:

Given that,

Jeremy finished 3 puzzles in 266 minutes.

The second puzzle took twice as long as first.

The third puzzle took twice as long as the second one.

Assume that, the first puzzle took x minutes.

So, Second puzzle took= 2x minutes.

Third puzzle took =2(2x) minutes

                             =4x minutes

According to the problem,

x+2x+4x=266

⇒7x=266

⇒x=38 minutes

The third puzzle took = (4×38) minutes
