We have sequence equation
a_n=a(n-1)+4.

In this case n is a natural number (1, 2, 3, ...).

So start inserting and computing value of
a_n given that you know the value of n and a.


a_1=2(1-1)+4=4 (first term)


</p><p>a_2=2(2-1)+4=6 \\</p><p>a_3=2(3-1)+4=8 \\</p><p>a_4=2(4-1)+4=10</p><p>

Hope this helps.
