Use the formula I = P x R x T
Where I=interest
P=principal investment
R=interest rate
T=time in years
In this case, we want to know R, so re-arrange the formula to get:
R = I / (P x T)
=456/ (1600x6)
=456/9600
=0.0475
=4.75%

500 invested for 5 years at 7% interest compounded annually becomes 701.28
If you invested 7580 and after 5 years you have 3126.75 then the annual interest rate is negative. It is -16.23%.
It was eight years.

To calculate the interest earned in one year, you can use the formula: Interest = Principal × Rate × Time. Here, the Principal is the initial amount of money invested or borrowed, the Rate is the annual interest rate (expressed as a decimal), and Time is the duration in years (which is 1 for one year). For example, if you have a principal of $1,000 and an annual interest rate of 5%, the interest earned in one year would be $1,000 × 0.05 × 1 = $50.

The word "more" is comparative and therefore there needs to be at least two scenarios that are being compared. There is only one given in the question.
If an amount C is invested for n years with an interest rate of r%, then the amount of interest earned is C*n*r/100
If the rate of annual interest is r% the period is n years and the amount invested is y Then the compound interest is y*(1+r/100)^n - y
