Answer:
122
Step-by-step explanation:
An arithmetic sequence means a number is added each term. There is a term for where a number is multiplied as well. But in this case the first number is -103, the second number is -94 and the third number is -85. Can you tell what number is added each time?
The number is 9. -103+9=-94 and -94+9=-85 and so on. Now we want a way to find the term way further down the line.
Think of it doing it all at once. -103+9+9 gets us the third term right? so that's 2*9. -103+3*9 would get us the fourth. Hopefully that makes sense, but let me know if it doesn't. But for a few more examples, if we want the fifth term we would do -103+4*9 and getting the tenth would need -103+9*9. So basically we take the number term we want (in this case we want the 26th) and then take -103+ n*9, where n is the term we want minus 1, or in this case 25. so that's -103+25*9
Let me know if you need more of an explanation.
Answer:
in all they spent 3 3/4 hours fishing and swimming in all
Step-by-step explanation:
if you know that they spent 1 1/4 hours fishing and that they spent twice that swimmin,
you can calculate the time spent swimming by doubling it:
1 1/4 hours is the same as 5/4 hours
doubled it is 10/4 hours that they spent swimming
all together, 10/4+5/4 is 15/4 hours which can be reduced to 3 3/4 hours
