Question 7 Explanation:
The difference is 6, 18, 36, 60.
These are multiples of 6 i.e.,
6 = 6 × 1
18 = 6 × 3
36 = 6 × 6
60 = 6 × 10
These are multiples of 6 i.e.,
6 = 6 × 1
18 = 6 × 3
36 = 6 × 6
60 = 6 × 10
→ The order is 1, 3, 6, 10, next one is 15. Like 1, 1+2, 1+2+3, 1+2+3+4, 1+2+3+4+5.
→ Next multiple = 6 × 15 = 90
→ 120 + 90 = 210
