Find explicit rules for the following recursive sequences:
a) an = 2(anâ1) + 4;a1 = 5
b) an = 6(anâ1)â8(anâ2);a1 = 1,a2 = 0

1. Write the first 15 terms of the sequencedefined by the following recursive formula:
A1=a2=1
An=an-1+an-2
I was able to manuallyplug in the numbers but woud like if there are explicit forumulas Ican use to get all the 15?
2.The nth triangular number Tn is given by the sumTn =1+2+3+
