Answer:
The explicit formula
The recursive formula
for 
if 
Step-by-step explanation:
If a sequence is arithmetical then the difference between any of its consecutive terms will be constant
3, 3.25, 3.5, 3.75,
The difference between the consecutive terms remains constant so the sequence is arithmetic.
The explicit formula for an arithmetic sequence is:
Where d is the constant difference between the terms.
is the first term of the sequence.
So
Finally, the recursive formula is:
Answer: do the math, 39x
Step-by-step explanation:2+4=6 times 7=42-19=23+7=30+9=39x
<u>Answer:</u>$68.69
<u>Step-by-step explanation:</u>
Calculation of bill value
Cheeseburgers = 26.25
(8.75 x 3)
Fish Sandwich = 6.75
Pizza = 14.99
Sweet Tea
(4 x 2.09) = 8.36
Total of items = 56.35
Sales tax on food = 3.381
(56.35 x 6%)
Total bill value = 59.731
Calculation of tips
Bill value x 15%
=59.731 x 15%
Tips paid=8.95965
Calculation of meals cost
Total meal cost = Bill value + tips
=59.731+8.95965
=$68.69
Total meal cost is $68.69
Answer:
x = -6 and x = 7
Step-by-step explanation:
x² - x - 42 = 0
find two number which
a + b = -1
a*b = -42
a = -7
b = 6
x² - x - 42 = 0
(x-7)(x+6) = 0
x-7 = 0
x = 7
x +6 = 0
x = -6
