Problem: what is the pattern? 9,19,34,44,51 what are the next 6 numbers
In the given sequence, we added 10, added 15, added 10 and added 7.
To get each successive step value, we added 5, subtracted 5 and subtracted 3.
Continuing that way, we get the following:
9 19 34 44 51 --- 63 70 74 83 87 88
+10 +15 +10 +7 --- +12 +7 +4 +9 +4 +1
+5 -5 -3 --- +5 -5 -3 +5 -5 -3
