Use the explicit formula an = a1 + (n - 1) • d to find the 500th term of the sequence below. 24, 31, 38, 45, 52, ... A.3545 B.3493 C.3524 D.3517
@ComputerNerd
@Robert136
Notice that it's an arithmetic sequence with equal intervals of 7.
wait what
oo so it goes by 7 ok
You want the 500th term. So the increase from n=1 will be 7*499+24 is your answer
somits d
so its d
3517
Yup
thx your really god at this stuff
good
No prob
i got one more
got more questions?
yea its kinda the same
go ahed
The explicit formula for the nth term of an arithmetic sequence is an = a1 + (n - 1) • d. What is the simple formula corresponding to the explicit formula if the first term of the sequence is -10 and the difference between terms in the sequence is 3? A. 3n + 10 B. 3n - 7 C. 3n - 10 D. 3n - 13 E. 3n + 13
note that difference between terms is always 3. And this quesiton is asking you to pick the equation when first term=-10
it think its c
All the other options are there to confuse the wits out of you:)
nice
omg ok this one is hard
First term is -10. So 3n+13
3n-13
n=1 3-13=10 right?
yea
do you know this one
D
Don't snitch on the losers
ik that but i have a different problem
Tile setters use small tiles in the shape of hexagons to create all sorts of decorative patterns. In the pattern below, a central red tile is surrounded by bigger and bigger six-sided rings of colored tiles. Only three colored rings are shown, but larger rings of white tiles surround the ones you see here. http://media.apexlearning.com/Images/200511/02/e747e661-53da-4b77-98f1-81817eb5af47.gif Don't count the red tile. The smallest ring has 6 blue tiles in it. The next ring has 12 yellow tiles. Count the number of green tiles in the third ring. Based on the pattern established by the first three rings, how many tiles are there in the 25th ring of white tiles, counting outward from the central red tile? A. 144 B. 150 C. 156 D. 125
i hate this problem
Oh I see
d=+1
so the 25th ring is144
I took d as the additional tile outside of the equation.
so iwas right :D
ill brb ima go eat
6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96,102,108,114,,120,126,132,138,144,150,156,162,168,174...
so 144
it says don't count on the red tile so that would be 150
100% positive it's B
You can count me on this
ok
