This is a pattern:
0, 1, 1, 2, 3, 5, 8, 13, 21, 42, 76, 139, 257, xy
Solve for y when x = 29.5.
Hint: At the ninth or tenth term the pattern rule changes. You might have thought of Fibonacci.
0, 1, 1, 2, 3, 5, 8, 13, 21, 42, 76, 139, 257, 472, 868, 1,597, 2,937, 5402.......etc.
After the 9th term, or 21, each subsequent term is the SUM of the previous 3 terms.
y=472/29.5=16
+425
