16points plz me i’m confused can you also explain you-if you can’t see it it says describe and finish the pattern i need asap

Subtract 20 then add 10,  repeating

The next 3 numbers are 70,50,60

Step-by-step explanation:

100,80, 90, 70, 80, 60

100,    80,     90,     70,    80,     60

    -20      +10    -20    +10   -20

We subtract 20 add 10 subtract 20 add 10  etc

The last thing we did was subtract 20 so we need to add 10 to 60

60+10 = 70

Now we subtract 20

70-20 = 50

Then we add 10

50+10 60

The next 3 numbers are 70,50,60
