Answer 1

Hello from MrBillDoesMath!

Answer:

Discussion:

I stared at the numbers 19, 29, 39, 49, 59, 69,... for a second and noticed that adding 10 to any number gives the next number to the right. For example,

19 + 10 = 29

29 + 10 = 39

39 + 10 = 49

etc.....

A recursive formula would be:

a(0) = 19        

a(n+1) = a(n) + 10    if n >= 0
