Question

write an explicit formula for the recursive formula:
a1=4a n-1 + 16

Answer 1

hmmm @lashae1995 would u plz check n see if u got everything in the eqn u posted above? seems like its missing something....

Answer 2

Or is it really just a_1 = a_n-1 +16? I think there should be the term a_n somewhere in the equation....

Answer 3

a1=4, an=a (n-1) +16

Answer 4

Ah thank you :)

Answer 5

a1=4
a2=a1+16
a3=a2+16=a1+16+16
...
a_n=a_(n-1)+16=a1+(n-1)*16

following so far?
