1.) in the fibonacci sequence each term after the first two terms is the sum of the preceding two terms. if the first two terms are 1 and 1, then what is the tenth term?

2.) find the geometric mean of 275 and 11

1) Tenth term of the Fibonacci sequence is 55.

2) The geometric mean of 275 and 11 is 55.

Step-by-step explanation:

1) Fibonacci sequence is a sequence in which each term after the first two terms is the sum of the preceding two terms.

Given: the first two terms are and

We have to find the tenth term of the Fibonacci sequence.

Adding first two terms,

Thus, tenth term of the Fibonacci sequence is 55.

b) To find the geometric mean of 275 and 11.

Geometric mean is a mean where we take the product of numbers and then take the nth root (n is the number of terms )

Geometric mean of two numbers a and b is

Here, a = 275 and b = 11

Thus, the geometric mean of 275 and 11 =

Thus, the geometric mean of 275 and 11 is 55.
