Answer: 142 and 286
==========================================
Step-by-step explanation:
If we multiply a given term by 2, then add 2, we get
7*2+2 = 14+2 = 16
16*2+2 = 32+2 = 34
34*2+2 = 68+2 = 70
So the rule seems to be "multiply by 2, then add 2"
If that rule holds up, then the next two terms are
70*2+2 = 140+2 = 142
142*2+2 = 284+2 = 286
