Add all the equations/side values together
Answer:
d
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
Here a = 3 and r = 12 ÷ 3 = 4 , thus
=
= = 65536 - 1 = 65535 → d
Answer:
p=(t-s)/r
Step-by-step explanation:
This is an equation so all we have to do is solve backwards step by step:
rp+s=t
rp+s-s=t-s
rp/r=(t-s)/r
p=(t-s)/r
Odd degree, negative leading coefficient.
