An investor invests $10 000 at x% p. a . compound interest for 2 years. He finds that he receives $20 more in interest than if he had invested it at a simple interest rate of x % p. a . Find x .

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110

answer is a.
