I think You should break it down to the First and third One because of
#11: First term is 2. Formula for the (n+1)th term is (previous term) + 3.
Thus, we have 2, 5, 8, 11, 14, ... This is an arithmetic sequence with common difference 3.
#12 First term is -4. Formula for the (n+1)th term is (previous term) + n^2.
Second term (n=2): -4 + (2^2) = 0
Third term (n=3) : 0+3^2 = 9
Fourth term (n=4): 9 + 4^2 = 25
Fifth term (n=5) : 25 + 5^2 = 50
A=p(1+i/m)^mn
A=26,000÷(1+0.06÷2)^(2×7)
A=17,189.06

Answer:
A=$538.82
Step-by-step explanation:
We're going to use the compounded interest formula:
A=P(1+r/n)^n*t
Where,
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = t is the amount of time at which you're checking how much it's worth (yrs)
Using this information, we can use:
A=500(1+0.025/4)^3*4
A=500(1+0.00625)^12
A=500(1.00625)^12
A=500(1.07763259886)
A=538.82
A=$538.82....
