The "rule of 72" says that the doubling time in years is approximately 72 divided by the interest rate in percent. To make the money grow by a factor of 4 requires that it double twice, so will take twice as long as the period to double once.
2×72/11.3 ≈ 12.7 . . . . years
_____
The "rule of 72" is an approximation. The actual quadrupling time for this interest rate and compounding is about 12.6 years. (The actual product of doubling time and nominal interest rate is about 71.25.)
Heyya
I think the pattern is (n+1)^5
1=1^5
32 = 2^5
243 = 3^5
1024 = 4^5
3125 =5^5
Then the next number should be 6^5 = 7776
Hope you get it
