### Instruction:
Two days ago, Uncle Welly planted 50 roses on his vacant lot. Yesterday, he planted 20 more roses than the previous day. Today, he planted twice the number of roses than two days ago. How many roses did Uncle Welly plant in his vacant lot?

### Response:
Two days ago, he planted 50 roses.
Yesterday, he planted 50 + 20 = <<50+20=70>>70 roses.
Today, he planted 50 * 2 = <<50*2=100>>100 roses.
In total, he planted 50 + 70 + 100 = <<50+70+100=220>>220 roses.
