Use colored counters to answer the question. Typically, black counters represent a profit or a positive number, while red counters represent a loss or a negative number. Here, use white in place of red, that is, consider a white counter to mean what a red counter would in the typical case.How many black counters and how many red counters (shown here in white) are there in a triangular array like this but with 16 rows?
