Directions:(1-5)

**Find the wrong term in the series given below.**##### 1. Question

161, 217, 306, 387, 711, 792

Ans:5

The pattern is as follows:161 + (1 + 6 + 1)

^{2}= 225225 + (2 + 2 + 5)

^{2}= 306306 + (3 + 0 + 6)

^{2}= 387387 + (3 + 8 + 7)

^{2}= 711711 + (7 + 1 + 1)

^{2}= 792##### 2. Question

30, 81, 308, 1515, 9050, 63329

Ans:4

The pattern is as follows:30 x 3 – 3

^{2}= 8181 x 4 – 4

^{2}= 308308 x 5 – 5

^{2}= 15151515 x 6 – 6

^{2}= 90549054 x 7 – 7

^{2}= 63329##### 3. Question

1229, 1373, 1525, 1685, 1851, 2029

Ans:2

The pattern is as follows:35

^{2}+ 4 = 122937

^{2}+ 4 = 137339

^{2}+ 4 = 152541

^{2}+ 4 = 168543

^{2}+ 4 = 185345

^{2}+ 4 = 2029##### 4. Question

8, 7.5, 21.0, 65.5, 265.0, 1328.5

Ans:1

The pattern is as follows:8 x 1 + 1.5 = 9.5

9.5 x 2 + 2.0 = 21.0

21.0 x 3 + 2.5 = 65.5

65.5 x 4 + 3.0 = 265.0

265.0 x 5 + 3.5 = 1328.5

##### 5. Question

64, 160, 400, 1004, 2500, 6250

Ans:2

The pattern is as follows:64 x 2.5 = 160

160 x 2.5 = 400

400 x 2.5 = 1000

1000 x 2.5 = 2500

2500 x 2.5 = 6250

##### 6. Question

Directions:(6-10)
