the first few bars are the people who walked fewer than 4,000, so add up the numbers on the side (2 and 5) and you get 7, so a
an=a1+d(n−1) is the explicit and a recursive formula for each sequence .
<h3>What is sequence?</h3>
See the pattern
-32-(-20) = -12
-20-(-8) = -12
-8-4 = -12
By this the explicit and a recursive formula for each sequence is an=a1+d(n−1).
An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.
Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.
An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

Answer:
hope this helps
Step-by-step explanation:
.55×78=42.9
78+42.9
=120.9 round off 121
The first step is to find the installation cost of each flooring.
let i be the instalation fee, and i2 and i3 correspond to scenarios 2 and 3
(1.73)(120)+i=740.40
(4.98)(200)+i2=1,688.00
(2.48)(180)+i3=928.80
i=532.8
i2=692.00
i3=482.4
ok, so we have the total installation cost for each room. Now we divide that by square feet.
532.8/120=4.44
692.00/200=3.46
482.4/180=<span>2.68

Ordering that from least to greatest, you get <span>Berber carpet, </span><span>hand-scraped hardwood, and slate tile, which has the greatest installation fee.
