15 goes into 48 3.2 times.
The sequence is formed from two interwoven series. 440, 216, 104, 48 ........Halve the number and subtract 4. 260, 128, 62, 29...........Halve the number and subtract 2. The next number would be generated by the first series 48/2 = 24 24 - 4 = 20..........which is the next number.
To find the number needed to add to 48 to reach 100, you would subtract 48 from 100, which equals 52. Therefore, you would need to add 52 to 48 to reach 100.
Yes, 48 times.
3 times, remainder 3
Not sure how you're getting -25, but when you are subtracting a bigger number from a smaller number the strategy is to swap the numbers and add a negative sign which would give you -15.
48 X 15 = 720.

The answer is 720.
This does not sound like an equation. This sounds like evaluating an algebraic expression. 3C means 3 times the value of C (which you have given as 21) then subtract 15. 3 x 21 - 15 = 48

48 whole times, with enough left over for about 0.59 of one more time.
