What are the next 3 numbers in this pattern? 24, 17, 10, 3, -4

**if could, please tell me how you found those numbers**

At the beginning of 1974/75,2 years a man invested #2000 in a bank at 12.5% compound interest, if it degree #650 at the end of each two years to pay his son's school fees, after payment of interest to pay his son's school fees, how much did he have left at the beginning of the 1978/79 school year?

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
