Answer:

  • Sn = n^2 . . . . . . the pattern
  • {1, 4, 9, 16, 25, 36, 49}

Step-by-step explanation:

The consecutive differences between S-numbers are (by definition) consecutive odd numbers. This by itself indicates that S-numbers are defined by a quadratic formula. As it happens, ...

  Sn = n^2

___

  S1 = 1 . . . . given

  S2 = S1 + 3 = 4

  S3 = S2 + 5 = 9

  S4 = S3 + 7 = 16

  S5 = S4 + 9 = 25

  S6 = S5 +11 = 36

  S7 = S6 +13 = 49

A list of the first 7 S-numbers is ...

  {1, 4, 9, 16, 25, 36, 49}
