Question

Create the formula for the geometric sequence of 1,4,16 , 64...​

Answer 1

The formula of a geometric sequence is
`a_(n)=a_(1) r^(n)`

• 
  `a_{1`: the first term of the sequence --> 1
• r: ratio of the sequence --> 4
• n: the position of the number that you want to find
• 
  `a_(n)` : the number at position 'n'

Equation is
`a_(n) =1*4^(n)`

Hope that helps!
