Answer Key-
Q-(1) Sol-(2)
213, 223, 233, 243, 253
Q-(2) Sol-(5)
5×6 = 30
30×5 = 150
150×4 = 600
600×3 = 1800
1800×2 = 3600
Q-(3) Sol-(1)
6×8 – 28 = 20
20×7 – 24 = 116
116×6 – 20 = 676
676 ×5 – 16 = 3364
3364×4 – 12 = 13444
13444×3 - 8=40324
Q-(4) Sol-(3)
5 × 2 + 1 = 11
11× 2 – 1 = 21
21× 2 + 1 = 43
43 × 2 – 1 = 85
85 × 2 + 1 = 171
Q-(5) Sol-(4)
1 + (11)2 = 122
122 + (12)2 = 266
266 + (13)2 = 435
