Study the number pattern carefully.
- What is the missing number in the 12th pattern?
- What is the missing number in the 29th pattern?
- If this number pattern goes on, which pattern number will give you 293?
(a)
Pattern 1: 1
2 + 4 = 5
Pattern 2: 2
2 + 4 = 8
Pattern 3: 3
2 + 4 = 13
Pattern 4: 4
2 + 4 = 20
Formula:
Number for each pattern = Pattern number
2 + 4
Missing number in 12th pattern
= 12
2 + 4
= 148
(b)
Missing number in 29th pattern
= 29
2 + 4
= 845
(c)
Pattern number
2 + 4 = 293
Pattern number
2 = 293 - 4 = 289
Pattern number
= √289
= 17
Answer(s): (a) 148; (b) 845; (c) 17
