To determine

To write:the verbal rule to describe the pattern and find the 10^th term.

Answer to Problem 34P

The number of players in 10 teams is 70.

Explanation of Solution

Given:

  

Calculation:

Observe the pattern,

The number of players in 1 team is 7 or $7\times 1.$

The number of players in 2 teams is $7+7$ or $7\times 2.$

The number of players in 3 teams is $7+7+7$ or $7\times 3.$

Thus, the number of players in n teams is $7\times n.$

Therefore, the number of players is equal to 7 times the number of teams.

Now, find the 10th term in this pattern.

  $\begin{array}{l}{10}^{th}\text{term}=7\times 10\\ =70\end{array}$

Conclusion:

Hence, the number of players in 10 teams is 70.
