Hi,
find the nth term in each of the linear sequences.
a%5Bn%5D+=+a%5B1%5D+%2B+%28n-1%29d
3,5,7,9,11,........a%5Bn%5D+=+3+%2B+%28n-1%292
8,12,16,20,........a%5Bn%5D+=+8+%2B+%28n-1%294
3,7,11,15,19,......a%5Bn%5D+=++3+%2B+%28n-1%294
draw graphs for the following pairs of equations on the same grid and hence solve the simultaneous equations.
y=4x-18
y=-6x+12
Looks like it is (3,-6) substitution verifies that
