Can you follow the mathematical progression to find the fifth number in the series listed below.


1.) 43 44 47 45 ___ 44 49 45 39




2.) 26 27 29 32 ___ 35 38 39 41

Bump

2) is probably 33 - would have intervals 1,2,3,1,2,3,1,2, etc

1) could be a double sequence where 44 and 45 alternate on one sequence and the other goes 43, 47, 41, 49, 39, 51 etc (+4 -6 +8 -10 +12 etc). The latter is itself a double sequence of 43,41,39... alternating with 47,49,51...

..or I could be talking drivel

I agree tatters on 1). The progression going +1, +3, -2,-4, +3, +5, -4, -6.
