PLS PLS PLS HELP IM BEHIND The first sequence rule is multiply by 3 starting from 4. The second sequence rule is add 8 starting
Alchen [17]

Answer:

36

Step-by-step explanation:

the first sequence starts

4 12 (3*4) 36 (3*12) 108 (3*36) ...

the second sequence starts

20 28 (8+20) 36 (8+28) 44 (8+36) ...

so, just by writing down a few elements you can see it already.

I knew it already before that just by thinking "the first sequence has only numbers that can be divided by 3. what is the first number of the second sequence that can be also divided by 3 ? oh, yeah, 36 !"
