Answer:
The first three terms is 64, 32, 16
Step-by-step explanation:
Given
Number of participants = 64
Decrement = 1/2
Required
Find the first three terms
To calculate the first three terms, we make use of the following formula;
Current Term = Previous Term - 1/2 * Previous Term
The first term = Initial number of participants
First Term = 64
Second Term = First Term - 1/2 * First Term
Second Term = 64 - 1/2 * 64
Second Term = 64 - 32
Second Term = 32
Third Term = Second Term - 1/2 * Second Term
Third Term = 32 - 1/2 * 32
Third Term = 32 - 16
Third Term = 16
Hence, the first three terms is 64, 32, 16
