Answer:
-84
Step-by-step explanation:
The formula for the nth term of a geometric progression is 
Un = ar^n- 1
The sum of the first six terms of a geometric series (U6) = 21/16 
Common ratio = -1/2 ,
a = First term ??
21/16 = a × (-1/2 )^6- 1
21/16 = a ×(-2^-1)^5
21/16 = a × -2^-6
Cross Multiply
16 × a × -2^-6 = 21 
a = 21/16 × -2^-6
a = 21/16 ×- 1/2⁶
a = 21/16 × -1/64
a = 21 ÷(-1/4)
a = 21 × -4
a = -84
The first term = 84

<h3>What are ratio and proportion?</h3>
A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
Shawn is collecting money from students at his school for a charity. 
The table gives the ratios of the number of students who have donated and the amount of money he has collected from them. 
Since 30 is 1/3 of 90, we know the ratio is 1:3.
