We first find A2, for which we multiply A with itself. We perform matrix multiplication in which we multiply rows of first matrix with columns of second matrix element by element and add.
For an arithmetic sequence, the nth term is the first term plus (n-1)×the differece
the first term is 28, the difference between each adjacent number is 8
so -36=(28)+8(n-1)
8(n-1)=64
n-1=8
n=9
the 9th term is -36
Answer:
The answer I got was 7 7/10
(sorry if wrong!)
3+1.50n would be an expression for this
The answer is -6 because the square root of 36 is 6, but then you have to add the negative in front of it.
