2 + 3 = 5

5

5 + 5 = 10

7

10 + 7 = 17

11

17 + 11 = 28

13

28 + 13 = 41

17

41 + 17 = 58

19

58 + 19 = 77

23

77 + 23 = 100

29

100 + 29 = 129

31

129 + 31 = 160

37

160 + 37 = 197

41

197 + 41 = 238

43

238 + 43 = 281

47

281 + 47 = 328

53

328 + 53 = 381

59

381 + 59 = 440

61

440 + 61 = 501

67

501 + 67 = 568
