• 4 = 2^2(2-1)
  18 = 3^2(3 - 1)
  100 = 5^2(5 - 1)
  294 = 7^2(7-1)
  so the next term is 11^2(11-1) = 1210

• 2, 3, 5, 7, 11 are prime numbers.
  
  2^3 - 2^2 = 8 - 4 = 4
  
  3^3 - 3^2 = 27 - 9 = 18
  
  5^3 - 5^2 = 125 - 25 = 100
  
  7^3 - 72 = 343 - 49 = 294
  
  11^3 - 11^2 = 1331 - 121 = 1210
  
  So, the next number is 1210.
