Find the 7th term of the sequence {eq}1, \frac12, \frac14, \frac18, . . . {/eq}

Question:

Find the 7th term of the sequence {eq}1, \frac12, \frac14, \frac18, . . . {/eq}

Geometric progression

The series at which next term is a multiplicative of preceding term is called geometric progression. Each and every term is related by a constant factor that is multiplied in each and every term to gives us geometric progression.

Given,

Geometric progression:

{eq}1,\dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}...... {/eq}

a = 1,r = {eq}\dfrac{1}{2} {/eq}

To find 7th term we know...
