I THINK its 2. :) Hope i'm right.
A(n) = current term
a(n + 1) = next term
in a geometric sequence, the next term comes from a product of the current term and the common ratio.
the common ratio can be any value, let's say use r = ½.
if the current term is say hmmm 40, the next term is 40*½ , or 20, so indeed, the next term is smaller.
Answer:
Step-by-step explanation:
this question has already been answered on gauth math
Step-by-step explanation:
a(n) = a +(n-1)d
a=20
d=26-20=6
°.° a(n) = 20 +(n–1)6
a(1) = 20 +(1–1)6=20
hope this helps
