The arrangement of the apples in the stack is in a sequence that can be
used to find the number of apples in each row and in the stack.
Correct response:
- The number of apples in the stack are <u>85 apples</u>
<h3>How to find the sum of a sequence</h3>
The given parameters are;
Dimensions of apples in the rectangular base = 7 apples by 5 apples
Number of apples on which each apple above rests = 4 apples
Required:
The number of apples in the stack.
Solution:
The dimensions, length and width of the apples in each row decreases
by 1 compared to the row on which the apple rests, as follows;
In the base, the dimension = 7 by 5
In the row directly above, the dimension = (7 - 1) by (5 - 1)
The number of apples sequence continues and is completed by a singles row of apples at the top, from which gives;
Number of apples in the stack = 7 × 5 + 6 × 4 + 5 × 3 + 4 × 2 + 3 × 1 = 85
- The number of apples in the tack = <u>85 apples</u>
