Consider the pattern.
- What is the sum of Row 6?
- What is the sum of Row 44?
- If the sum is 841, what is the row number?
(a)
Pattern for the sum of each row
Row 1: 1
2 = 1
Row 2: 2
2 = 4
Row 3: 3
2 = 9
Formula:
Sum of each row = (Row number)
2 Sum of Row 6
= 6
2 = 6 x 6
= 36
(b)
Sum of Row 44
= 44
2 = 44 x 44
= 1936
(c)
Row number = √(Sum of each row)
Row number with the sum 841
= √841
= 29
Answer(s): (a) 36; (b) 1936; (c) 29
