1. Find the 9th term of this sequence: a(n) = 5n - 8
2. Find the sum of the first 4 terms of the sequence in question 1.

Please help ASAP

Step-by-step explanation:

substitute n with the numbers

btw, follow bodmas/pemdas

e.g., 5*1(n)-8= -3

so (5*9)-8=37

and the sum of the first 4 is

-3+2+7+12=18

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.
