Plz asap, giving brainliest!

the first term in an arithmetic sequence is -1. the fourth term in the sequence is -4. the tenth term in the sequence is -10. which function can be used to find the nth term of the arithmetic sequence?
a) f(n) = 1/2(n + 5) + 2
b) f(n) = n + 4
c) f(n) = -3n + 8
d) f(n) = -n

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
