3x-12=-5
3x=7
x=7/3
100 ---> 96 is -4
96 ---> 104 is +8
104 ---> 88 is -16
88 ---> 120 is +32
120 ---> 56 is -64
So first we go down by 4, then up by 8, then down 16, then up 32, then finally down 64.
The pattern of numbers is: -4, +8, -16, +32, -64
Notice it's the powers of 2:
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
2^6 = 64
each term doubles. Also each term alternates in sign. One is positive, then the next is negative and so on.
The last difference is -64, which doubles to -128. Change the sign to positive to get +128
Add 128 to the last term of 56 to get
128+56 = 184
Therefore, the final answer is 184

Answer and step-by-step explanation:
20. Because the discount is 20% of the given price so the discount would be"
228/100*20
= 45.6 Rs
Its selling price would be:
228 + 45.6 = 273.6 Rs
21. Sales tax would be:
450/100*5
= 22.5 Rs
Total price in bill = 22.5 + 450 = 472.5 Rs
22. 10% tax of 3300 would be:
3300/100*10 = 330 Rs
Price before tax = 3300 - 330 = 2970 Rs
23. He spent in total of:
2500 + 500 = 3000Rs
He sold for 3300 Rs
He gain 3300 - 3000 = 300 Rs profit
His loss gain percent = 3300/3000 * 100 = 110%
24. On the first bike, he earn:
2500/100*20 = 500 Rs
On the second bike, he lose:
2500/100*25 = 625 Rs
He lose in total of 625 -500 = 125 Rs
his loss percentage = (2500+500) + (2500 - 625) / 5000* 100
= 100% - (2500+500) + (2500 - 625) / 5000* 100
= 100% - 97.5%
He lose 2.5% money
