Step-by-step explanation:
Answer:
use the formula sn= n(a1+an)/2
Step-by-step explanation:
2982=28(228+an)/2
5964=28(228+an)
5964/28=228+an
213=228+an
an=-15(last term)
to find difference use formula
an = a+(n-1)d
-15=228+(28-1)d
-243=27d
d=-243/27
d=-9
arithmetic sequence can be found be keep on subtracting 9 from 228
hence the arithmetic sequence is
228, 219, 210, 201, 192, 183, 174........-15
Answer:
The fourth line will have 15 marbles
Step-by-step explanation:
The third line has 7 marbles. So, you double that and add one in order to find the number of marbles in the fourth line.
7*2=14
14+1=15
Answer: y=2x+8
Step-by-step explanation:
(2,12)=(x1,y1)
(-7,-6)=(x2,y2)
(y2-y1)/(x2-x1)=(-6-12)/(-7-2)=-18/-9=2=m
y=mx+b
y=2x+b
insert (2,12) to y=2x+b
12=2*2+b
12=4+b
8=b
y=2x+8
