1. Correct answer is a (since when you are not given the n values, it is implied that the first value is 1).
3. Correct answer is a (a(n)=-3+4(1-1)=-3).
7. The pattern is to reduce the previous value by 4, thus the 12th term of the sequence is -24 (a(n)=20 - 4(n-1)=20 - 4(12-1)=-24).
8. Missing term is 26 (32+20=52; 52/2=26).
10. Pattern is 625/1=625; 625/5=125; 125/5=25; 25/5=5, thus. the 10th term is 1/3125 (answer a).
16.
1/2= 0.5 and it takes 16 months to get to 8 inches.
0.5x16=8
C. (5, -11) hope this helps and I’m like sure sure it’s right
Answer:
The two numbers are 13 and 6.
Step-by-step explanation:
x+y=19
x-y=7
-----------
2x=26
x=26/2
x=13
13+y=19
y=19-13
y=6
x=13, y=6.
It would be 7.62 centimeters. Just multiply how many inches you have by 2.54, and you'll have your conversion.
