Study the following pattern.
- In which column will the number 135 appear?
- What number will appear in row 115 column 6?
(a)
Numbers in two rows = 7
Row where the number 135 will appear in
= 135 ÷ 7
= 19 r 2
Row 135 will appear in column 4.
(b)
Number of numbers in 114 rows
= 114 ÷ 2 x 7
= 399
Number that will appear in row 115 column 6
= 399 + 3
= 402
Answer(s): (a) 4; (b) 402
