Find nth term of Geometric Sequence a = 1, n = 8, and r =2 easily by taking help of our easy yet handy Geometric Sequence Calculator and get the result 128 easily.

## The nth term of Geometric Sequence a = 1, n = 8, and r =2 is 128

Steps to find nth term of geometric sequence:

**nth term of geometric sequence formula:-**

a_{n} = a * r^{(n-1)}

**where:**

- a
_{n}is the nth term - a is first term
- n is total number of terms
- r is common ratio

**Input values are:-**

a = 1

n = 8

r = 2

**Put values into formula**

a_{n} = a * r^{(n-1) }

a_{8} = 1*2^{ (8-1) }

**a _{8} = 128**

Below is the step by step procedure to determine the nth term of Geometric Progression(G.P) a = 1, n = 8, and r =2. Follow this detailed process and arrive at the solution easily.

- Firstly, identify the given terms of the sequence i.e. a = 1, n = 8, and r =2
- Now, substitute the know values in the formula of finding nth term of Geometric Sequence i.e. a
_{n}= a*r^{(n-1)}= a_{5}= 1*2(8-1) - Simplifying further we get the resultant value a
_{5}= 128
