Fill in the number according to the rule. 0,8,24,48, (), 120

Fill in the number according to the rule. 0,8,24,48, (), 120

0+8=8
8+8×2=24
24+8×3=48
So:
48+8×4=80
80+8×5=120
It's 80

Ask me a few questions about number reasoning 0 6 24 60 120 () 2 7 14 21 294 ()

The result of the first question should be 210,6-0 = 1 * 6,24-6 = 3 * 6,60-24 = 6 * 6120-60 = 10 * 6. The difference of the multiples of 6 in each result is an arithmetic sequence, that is, 3-1 = 2,6-3 = 3,10-6 = 4. Let the evaluated value be m, then M-120 = (10 + 5) * 6, that is, M = 210
The result of the second question should be 315,2 * 7 = 14,7 + 14 = 21,14 * 21 = 294, so the next one is 21 + 294 = 315

Fill in the following () with the same number to make the equality 24 * () - () * 15 = 18

24*x-x*15=18
x*(24-15)=18
x*9=18
x=2
