You made a typo. You typed an equal sign 
when you should have typed either a plus +
or a minus -.

If the second equal sign was supposed to be a +, and you meant



Then for n=1, you just put down a%5B1%5D=4 from the first equation

Then for n=2 you have a%5B2%5D+=+a%5B2-1%5D%2B3+=+a%5B1%5D%2B3+=+4%2B3+=+7

Then for n=3 you have a%5B3%5D+=+a%5B3-1%5D%2B3+=+a%5B2%5D%2B3+=+7%2B3+=+10

Then for n=4 you have a%5B4%5D+=+a%5B4-1%5D%2B3+=+a%5B3%5D%2B3+=+10%2B3+=+13

First four terms are 4,7,10,13

Then for n=2 you have a%5B2%5D+=+a%5B2-1%5D-3+=+a%5B1%5D-3+=+4-3+=+1

Then for n=3 you have a%5B3%5D+=+a%5B3-1%5D-3+=+a%5B2%5D-3+=+1-3+=+-2

Then for n=4 you have a%5B4%5D+=+a%5B4-1%5D-3+=+a%5B3%5D-3+=+-2-3+=+-5

First four terms are 4,1,-2,-5
