Mikayla is building a pyramid of paper cups. The bottom row has 61 cups while the top row has only one cup. If there are 16 tota
worty [1.4K]

The number of cups will be equal to 496.

<h3>What is arithmatic progression?</h3>

The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmatic progression

Here we have the data:-

The bottom row has 61 cups

If there are 16 total rows

The number of the cups will be calculated as:-

S_n=\dfrac{n(a_1+a_n)}{2}

Here a1 is first term 1

an is last term 2

n is the total number of the rows

By putting the values in the question we will get:-

S_n=\dfrac{16(1+61)}{2}=\dfrac{16\times 62}{2}=496\ cups

Hence the number of cups will be equal to 496.
