First tell us what an AP is.
Arithmetic Progression?
use your two formulas for the general term of an AP and the sum of terms of an AP
a+3d + a+7d = 24 ----> 2a + 10d = 24
and
6/2[2a + 5d] + 10/2[2a+9d] = 44
now solve these two equations in two unknowns
If you are talking about arithmetic progressions, this one has the properties you require:
-13 -8 -3 2 7 12 17 22 27 32 ...
