4 + x² = 25
21 = x²
x = 4.58258

Answer:
a₁ = 1
r = 3
Step-by-step explanation:
Since it’s a geometric series then
a₁ = 1 ( because 1 is the first term of the series)
3/1 = 9/3 = 27/9 = 81/27 = 3 then r=3.

To find the value of a variable you must know the basics of pre-Algebra. 
Example: 
2x+9=39
To find he answer of this you must subtract 9 from both sides 
Then you are left with…
2x=30
Since 2x=30 means 2 times x equals 30
You can divide 2 from both sides to find the answer 
Which is…
x=15
