On the first day Chandra saw 2 monsters and on day 2 she saw twice that amount, 2 x 2 = <<2+2=4>>4 monsters seen on day 2.
On day 3 she saw double that amount of monsters, 4 x 2 = <<4*2=8>>8.
On day 4 she saw double that amount of monsters, 8 x 2 = <<8*2=16>>16.
On day 5 she saw double that amount of monsters, 16 x 2 = <<16*2=32>>32.
Altogether Chandra saw 2 + 4 + 8 + 16 + 32 lost monsters = <<2+4+8+16+32=62>>62 total lost monsters that Chandra needs to lead back to the swamps.
