Answer 2

Answer:

The next number is 141.

Explanation:

50 , 50 + 1² = 51

51 , 51 + 2² = 55

55 , 55 + 3² = 64

64 , 64 + 4² = 80

80 , 80 + 5² = 105

so,

105 , 105 + 6² = 105 + 36

                       = 141

You can conitnue the series:

141 , 141 + 7² = 190

190 , 190 + 8² = 254  (like this)

50 , 51 , 55 , 64 , 80 , 105 , 141 , 190 , 254, ...
