The answer is A. 5/12
Hope it helped!
Answer:
28 - 4n
Step-by-step explanation:
What is the recursive formula for this sequence? 24,20,16,12
the sequence first term is 24
a= 24
Common difference (d) = T2 - T1 = T3 - T2
d = 20-24 = 16 -20
d = -4
Formula for nth term
Tn = a + (n-1)d
Tn = 24 + (n -1)-4
Tn = 24 -4n + 4
Tn = 28 - 4n
= 28 - 4n

Recall the logarithm rules :
a^y = x is the same as log_a x = y
In this case,
a = 18
y = r - 10
x = 93
So,
18^ (r-10) = 93
is the same as
log_18 93 = r - 10
Solve for r to get :
10 + log_18 93 = r
