1. Question

Directions:(1-5) Find the wrong term in the series given below.

161, 217, 306, 387, 711, 792

Correct

The pattern is as follows:

161 + (1 + 6 + 1)^{2} = 225

225 + (2 + 2 + 5)^{2} = 306

306 + (3 + 0 + 6)^{2} = 387

387 + (3 + 8 + 7)^{2} = 711

711 + (7 + 1 + 1)^{2} = 792

Incorrect

The pattern is as follows:

161 + (1 + 6 + 1)^{2} = 225

225 + (2 + 2 + 5)^{2} = 306

306 + (3 + 0 + 6)^{2} = 387

387 + (3 + 8 + 7)^{2} = 711

711 + (7 + 1 + 1)^{2} = 792

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

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
