Notice the following pattern:

2 - 0 = 2

6 - 2 = 4

12 - 6 = 6

20 - 12 = 8

It's reasonable to assume that consecutive terms in the sequence differ by increasing multiples of 2, so that for the next number (call it x) we expect to see

x - 20 = 10 ==> x = 30

and for the number after that (call it y) we would see

y - x = y - 30 = 12 ==> y = 42

Effective Rate find the effective rate of interest corresponding to a nominal rate of 7.5% per year compounded.

Jlenok [28]

Answer:

(A) 7.5 %

(B) 3.75 %

(D) 0.625 %

Step-by-step explanation:

We have given effective rate of interest r = 7.5%

(a) Annual rate of interest will be equal to 7.5 %

(B) As we know that 1 year = 12 months

And interest is compounded semiannually

1 semiannual = 6 months

So semiannual rate of interest will be equal to $\frac{7.5}{2}=3.75$ %

So number of period in an year = 3

So rate of interest quarterly $=\frac{7.5}{3}=2.5$ %

(D) Amount when amount is compounded monthly '

So number of period in an year = 12

So rate of interest $=\frac{7.5}{12}=0.625$ %

Step-by-step explanation:

Tip: When $log_{a} b = c$ , $a^{c} =b$ is also true.

$log_{z+5} (9) = 3x+4$ | <em>Original equation</em>

$(z+5)^{(3x+4)} = 9$ | <em>Use tip</em>
