First either add or subtract the number in the parenthesis (3^2-4) which equals to 5

90/[10+5) add the number in the parenthesis again (always do the parenthesis first) [10+5]= 15.

lastly divide 90/15 which equals to 6
always remember (PEMDAS)

What are the values of a 1 and r of the geometric series? 1 3 9 27 81.

sp2606 [1]

For the given geometric series the value of the common ratio(r) is 3, while the value of a₁ is 1.

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

A series of numbers whose any two consecutive numbers are always in a common ratio of that series.

Given to us

Series, 1 3 9 27 81

To find the value of the common ratio(r), we will simply find the ratio of any two consecutive numbers, therefore,

$r = ratio = \dfrac{3}{1} = 3$

As we can see the common ratio of the given series is 3, therefore, every next number will be thrice the number before.

We need to find the value of a₁ for the given series, and as we know that a₁ is the first number of the series with which the series is starting, therefore,

a₁ = 1

Hence, for the given geometric series the value of the common ratio(r) is 3, while the value of a₁ is 1.
