Study the following pattern.
- In which column will the number 142 appear?
- What number will appear in row 43 column 6?
(a)
Numbers in two rows = 7
Row where the number 142 will appear in
= 142 ÷ 7
= 20 r 2
Row 142 will appear in column 4.
(b)
Number of numbers in 42 rows
= 42 ÷ 2 x 7
= 147
Number that will appear in row 43 column 6
= 147 + 3
= 150
Answer(s): (a) 4; (b) 150
