In an arithmetic sequence, the 7th term is 30, and the 11th term is 60. What is the 21st term of this sequence?

135

Step-by-step explanation:

7th term ;a + 6d = 30

11th term; a + 10d = 60

solving simultaneously,a= -15 ,d= 7.5

21st term = a + 20d= 135

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
