Step-by-step explanation:
⇒12)It is an arithmetic sequence.
d=2-1=3-2=4-3=1
a(n) = a +(n-1)d
a(n) = 1+(n-1)1
The next three terms:
a(6) = 1+(6-1)1=6
a(7) = 1+(7-1)1=7
a(8) = 1+(8-1)1=8
⇒13)It is an arithmetic sequence.
d=0-3=-3-0=-6+3=-3
a(n) = a +(n-1)d
a(n) = 3+(n-1)-3
The next three terms:
a(5) = 3+(5-1)-3=-9
a(6) = 3+(6-1)-3=-12
a(7) = 3+(7-1)-3=-15
⇒14)It is <u>not </u>an arithmetic sequence.
⇒15) a(50) = 10 +(50-1)5
=<u>255</u>

Answer:
9.3%
Step-by-step explanation:
Given data
Principal=$11200
Futute value= $14345
Time= 3years
The simple interest expression is given as
A=P(1+rt)
substitute
14345=11200 (1+r*3)
14345=11200+r33600
14345-11200=r33600
3145=r33600
r= 3145/33600
r=0.093
Hence the rate is 9.3%
Interest is 3.20 per 100
3.2 × 275/100
=3.2 × 2.75
answer A $8.80
780 I think. Just do 13 times 60 maybe
