Ans:5 • ##### 2. Question

18, 19, 40, 123, 496, 2485, ?

Ans:3
18
18*1+1 = 19
19*2+2 = 40
40*3+3 = 123
123*4+4 = 496
496*5+5 = 2485
2485*6+6 = 14916
• ##### 3. Question

• ##### 6. Question

18, 20, 44, 138, 560, 2810, ?

Ans:4
The pattern of the series can be judged by the logical sequence given below:18 * 1 + 2 = 20
20 * 2 + 4 = 44
44 * 3 + 6 = 138
138 * 4 + 8 = 560
560 * 5 + 10 = 2810
2810 * 6 + 12 = 16872

Note: After getting the idea of pattern, no need to exactly calculate the last number (we can clearly understand that 2 will come at the unit digit place, so mark the answer as 16872)

• ##### 7. Question
