Question

completeaza sirurile: 221, 300, 331,600, 441, 1200,.....,......,......,.....

Answer 1

221, 300, 331, 600, 441, 1 200, 551, 2 400, 661, 4 800 .


331 = 221 + 110
600 = 300+300

441 = 331 + 110
1 200 = 600 + 600

551 = 441 + 110
2 400 = 1 200 + 1 200

661 = 551 + 110
4 800 = 2 400 + 2 400

Answer 2

221; 300; 331; 600; 441; 1 200; 551; 2 400; 661; 4 800; 771; 9 600; 881;

1 200 = 2 × 600

441 + 110 = 551

2 × 1 200 = 2 400

551 + 110 = 661

2 × 2 400 = 4 800

661 + 110 = 771

2 × 4 800 = 9 600

771 + 110 = 881
