Question

What's the conjecture for the sequence 3, 16, 42, 94, 198?

Answer 1

Answer:

406

Step-by-step explanation:

If we subtract the the the values in this sequence.

We get 13(16-3)

26(42-16)

52(94-43)

104(198-94)

From this we can take that these are doubles of each number.

So the double of 104 is 208.

When it is added with 198 it gives 406.
