Explanation

10, 14, 19, 28, 54, ?

Find differences:

14 - 10 = 4

19 - 14 = 5  

28 - 19 = 9

54 - 28 = 26

Differences: 4, 5, 9, 26

Look at the pattern in differences:

4 = 2^2

5 = 2^2 + 1

9 = 3^2

26 = 5^2 + 1

The next logical difference is 7^2 = 49

So next term = 54 + 49 = 103

Explanation

Check the pattern:

66 to 64 = -2

64 to 70 = +6

70 to 68 = -2

68 to ? = +6

So it alternates: -2, +6, -2, +6...

Next step after 68 should be +6

68 + 6 = 74
