Simplest recursion formula:

matrix%281%2C3%2C+++++a%5Bn%5D=2%2Aa%5Bn-1%5D%2C%22%2C%22%2Ca%5B1%5D=1%29

Simplest general formula

matrix%281%2C3%2C++++a%5Bn%5D=2%5E%28n-1%29%2C%22%2C%22%2Cn=%221%2C2%2C...%22%29

You can write the first one this way

matrix%281%2C3%2C+++++a%5Bn%2B1%5D=2%2Aa%5Bn%5D%2C%22%2C%22%2Ca%5B1%5D=1%29

You can write the second one this way:

matrix%281%2C3%2C++++a%5Bn%5D=2%5En%2C%22%2C%22%2Cn=%220%2C1%2C2%2C...%22%29
