Answer:
a₁ = 10
Step-by-step explanation:
The common difference d is calculated as
d = a₃ - a₂ = - 20 - (- 5) = - 20 + 5 = - 15
Then
a₂ - a₁ = d , that is
- 5 - a₁ = - 15 ( add 5 to both sides )
- a₁ = - 10 ( multiply both sides by - 1 )
a₁ = 10
Five to the power of 10 would be 9765625, so the scientific notation would be
9.765625 * (10^6), I think.
(I haven't done scientific notation in a long time, but I'm relatively sure that is what it is.)
Hope this kind of helped!
Formula :
Base²= Hypotenuse² - Perpendicular ²
Remember the a² in formula has nothing to do with the a we have to find. :)
