Answers with Explanation:-
1. (A)
The given series is : 13 – 1, 23 – 2, 33 – 3, 43 – 4, 53 – 5, 63 – 6,
So the missing term = 73 – 7 = 343 – 7 = 336 .
2. (D)
The pattern is + 3, + 5, + 3, + 5, …………
So the missing term is = 30 + 5 = 35 .
3. (A)
The pattern is + 6, + 9, + 12, +15 ………..
So the missing term is = 21 + 12 = 33 .
4. (C)
The pattern is +4, +8, +16, +32, +64
So the missing term is = 30 + 16 = 46 .
5. (B)
5 x 11 = 55, 55 x 11 = 605, 605 x 11 = 6655, 6655 x 11 = 73205
6. (A)
25 x 4 = 100, 100 x 4 = 400, 400 x 4 = 1600, 1600 x 4 = 6400.
7. (A)
125 = 53 , 216 = 63, 343 = 73, 512 = 83, 729 = 93, 1000 = 103.
8. (B)
13 , 33 , 53 , 73 , 93 , 113
9. (D)
121 = 112, 144 = 122, 169 = 132, 196 = 142, 225 = 152.
10. (D)
2025 = 452, 2116 = 462, 2304 = 482, 2401 = 492, 2500 = 502
