Given that:
a1=27, an=(an-1)+4
the second term will be:
a2=a1+4
a2=27+4=31
The explicit formula for arithmetic sequence is given by:
an=a+(n-1)d
where:
a= first term
d=common difference
n=nth term
from the information given:
a=27
d=31-27=4
thus the explicit formula will be:
an=27+(n-1)4
an=27+4n-4
an=23+4n
Answer: an=23+4n
Answer:
Step-by-step explanation:
Expand brackets.
This is in quadratic form.
Since this is for equal roots:
Plug k as 0 to check.
False.
So that means k must equal 6.
19 days are left in a year because 1 week=7 days which means 2 weeks=14 days 14 +5=19
Given ,
Hockey team wants to sell 500$ worth of tickets
Cost of each ticket = $10
To meet its goal ,
Number of tickets to be sold = total cost/cost of one ticket
=> Number of tickets to be sold = 500/10 = 50 tickets .
