Answer: -287
Step-by-step explanation:
The given pattern: 9, 1, -7, -15, ….
We observe that ,
First term : a=9
Common difference between the terms= 1-9=-8
For Arithmetic sequence , the formula to find the nth term is given by :-

Then, 38th term will be :-

Hence, the 38th term of the sequence.= -287
Answer:
972
Step-by-step explanation:
9x8 = 72
9x 100 = 900
(you can use a calculator)
10% of 10 is 10%*10 which is 1 :)
