Ответ:
The sequence is adding by three
Ответ:
your answer is multiplying by 2
Ответ:
a(1)=1
a(n)=a(n-1)+14
Step-by-step explanation:
The first term is 1, so a(1) = 1
Now, the second term, n=2 which means a(2)=a(1)+x
a(2)=1+x
also a(2)=15, then 1+x=15, and x=14
We can also check using a(3), a(4), and it fits.
