It's a four step sequence. 1 is called the initial/start or seed number.

Start with 1

....................................................

Step 1 : Double the previous number

Step 2 : Add 2

Step 3 : Subtract 1

Step 4 : Return to Step 1

16 occurs after Step 2 so it is followed by 15,30,32,31,62,64.........etc

What is the answer to this number seequence 1 2 4 3 6 8 7 14 16?

The sequence alternates between two patterns: one where numbers are doubled (1, 2, 4, 8, 16) and another where numbers decrease by 1 after each doubling (3, 6, 7, 14). Following this pattern, after 16, the next number should be 15, which continues the decreasing pattern. Thus, the answer to the sequence is 15.

What is the number after 15 24 25 5 14 15?

The given sequence uses numbers that correspond to letters in the alphabet (A=1, B=2, ..., Z=26). Translating the numbers, we get O (15), X (24), Y (25), E (5), N (14), O (15). The next letter after O (15) would be P (16), so the next number in the sequence is 16.
