What is the summation notation for the geometric series 1/2+2+8+32+128?

Karolina [17]

The summation notation is ∑ $(4^{n} -1)\\$ /2.

<h3>What is geometric progression?</h3>

The common ratio multiplied here to each term to get the next term is a non-zero number.

Given: 1/2+2+8+32+128

Using,

$a_n= a_1r^{n-1}$

We have,

a1 =1/2 and r= 4

notation is : An= ∑ $(4^{n} -1)\\$ /2

Hence, the notation is An= ∑ $(4^{n} -1)\\$ /2.
