Answer:

Step-by-step explanation:

Answer:
nth term = 7n - 2
Step-by-step explanation:
a = first term = 5
d = common difference = second term - first term
= 12 - 5 =7
d = 7
a + (n-1)d
= 5 + (n -1)7
= 5 + 7n - 7 {add like terms}
= 7n - 2

Answer:
rate = natural log (Total / Principal) / Years
rate = natural log (2) / 4
rate = 0.69314718056 / 4
rate = 0.1732867951 So the required rate is
17.32867951 %

The first is to decouple the 10 into 2 * 5 and extract the values within the root. The other is to enter all the values to the same root and calculate in general
