Study the following pattern.
- In which column will the number 142 appear?
- What number will appear in row 49 column 2?
(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 48 rows
= 48 ÷ 2 x 7
= 168
Number that will appear in row 49 column 2
= 168 + 1
= 169
Answer(s): (a) 4; (b) 169
