Answer:
Part A
Part B
Geometric Sequence
Part C
1/4,3/4,5/4,7/4,9/4
Part D:
Step-by-step explanation:
By definition, an Arithmetic Sequence holds the same difference between each following number.
Part A
<u>Explicit Formula</u>
To write an explicit formula is to write it as function.
<u>Recursive Formula</u>
To write it as recursive formula, is to write it as recurrence given to some restrictions:
Part B
Geometric Sequence, since 2*2=4 8*2=16 and 16*2=32 and 8+2=10 8+16=24
Part C
Arithmetic Sequence, difference
<u>Explicit Formula:</u>
<u>Recursive Formula</u>
Part D
(1.1,1.5,1.9,2.3,2.7) Arithmetic Sequence, difference d=0.4
<u>Explicit formula</u>
<u>Recursive Formula</u>
4 is the x1 value, -8 is the y2 value, 8 is the x2 value, and 5 is the y2 value.
Change the messy words into numerals
3 times a number minus 2 equals 13
3 × n - 2 = 13
3n - 2 = 13
take 2 to the other side
3n - 2 + (2) = 13 + (2)
3n = 15
Divide by 3 on either sides to isolate n
= 
3 and 3 cancels out
n = 5
check:
3 times 5 minus 2 equals 13
3 × 5 - 2 = 13
15 - 2 = 13
13 = 13
The number is 5
