Find nth term of Geometric Sequence a = 1, n = 9, and r =2 easily by taking help of our easy yet handy Geometric Sequence Calculator and get the result 256 easily.

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

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

a = 1

n = 9

r = 2

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

a_{9} = 1*2^{ (9-1) }

**a _{9} = 256**

Below is the step by step procedure to determine the nth term of Geometric Progression(G.P) a = 1, n = 9, 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 = 9, 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(9-1) - Simplifying further we get the resultant value a
_{5}= 256

** 1. What is the formula for nth term of Geometric Progression?**

The formula for nth term of Geometric Progression is given by the equation a_{n} = a*r^{(n-1)}

You can find the nth term of Geometric Sequence a = 1, n = 9, and r =2 by substituting in the formula of nth term of G.P i.e. an = a*r^{(n-1)} = a_{5} = 1*2^{(9-1)}
