Answer:
Most of the combination reactions are exothermic but not all the combination reactions are exothermic similarly most of the decomposition reactions are endothermic but not not all the reactions are endothermic. For Example oxidation of hydrocarbons is exothermic.
 
2Mg + O2 -> 2MgO
Mg + 1/2 O2 -> MgO
