The change of base formula allows you to write a logarithm in terms of logarithms with another base. It follows this pattern,
where a≠1 and b≠1
Assigning the base to be 7,
I hope I was able to answer your question. Have a good day.
Answer:
the sequence is 2, 14, 98, 686.
Step-by-step explanation:
As we know in any geometric sequence the terms are denoted by
We have to find the first four terms of geometric sequence which has first term a = 2 and common ratio of the terms r = 7
number of terms = 4
The sequence from the formula will be
or the sequence is 2, 14, 98, 686.
I believe it is 30
