Answer:
144
Step-by-step explanation:
If you look at the pattern you would assume that before the first 1 in the pattern is 0 so to make the second number in the pattern you showed you would just add 1+0 which equals 1 which is the next number in your pattern. so then look at the number 2 you would just add the number behind it, which is 1, to make the number 3 you continue doing this (adding the number behind it) till you reach the tenth year which would be 144.
1, 1, 2, 3, 5, 8, 13
0+1=1 1+1=2 2+3=5 5+8=13 13+8=21 21+13=34 34+21=55 55+34=89 89+55=144
