Answer 2

Answer:

The next number is 254

Step-by-step explanation:

We have,

29,29,30,38,65,129...

Now if we notice,

29 + 0³ = 29 + 0 = 29

29 + 1³ = 29 + 1 = 30

30 + 2³ = 30 + 8 = 38

38 + 3³ = 38 + 27 = 65

65 + 4³ = 65 + 64 = 129

Then, we can just guess that next number will be 5³

So,

129 + 5³ = 129 + 125 = 254

Hence,

The next number is 254

We can only notice it if we take the difference of the numbers. But it could get complicated so I suggest a simple way.

Hope it helped you and believing you understood it....All the best
