The expression to find the sum of terms of the series is; Sₙ = 3(1 - ¹/₂ⁿ)

<h3>How to solve Geometric series?</h3>

We are given the series;

3/2 + 3/4 + 3/8 + 3/16 +.....

Formula for the nth term of a geometric series is;

aₙ = ar^(n - 1)

where;

a is first term

r is common ratio

From our given series;

a = ³/₂

r = (³/₄)/(³/₂) = ¹/₂

We know that Sum of GP when n < 1 is;

Sₙ = a(1 - rⁿ)/(1 - r)

Thus;

Sₙ = ³/₂(1 - ¹/₂ⁿ)/(1 - ¹/₂)

Sₙ = 3(1 - ¹/₂ⁿ)

Thus, the expression to find the sum of terms of the series is; Sₙ = 3(1 - ¹/₂ⁿ)

During the first hour of this stage, the nurse would assess the woman's fundus every 5 minutes.

<h3>What is Fundus?</h3>

This is referred to the internal structure of a hollow organ such as the uterus in this case. it is usually located at the bottom or the area which is located opposite the aperture of the hollow organ.

It should be checked every 5 minutes to measure the level of contractions and retractions which takes place in the uterus. This is done so as to know the right time for the fetus to be moved to the birth canal during labor of the pregnant female.

The fetus is then expunged to the vagina where the safe delivery of the baby takes place through the help of healthcare or experienced professionals.This is therefore the reason why the fundus should be checked at every 5 minutes interval.
