Complete the series 6, 24, 60,120, 210, ?

336

366

660

correct answer a

First Number = 1 *2 *3 = 6
Second Number = 2*3*4 = 24
Third Number = 3*4*5 = 60
Fourth Number = 4*5*6 = 120
Fifth Number = 5*6*7 = 210
Sixth Number = 6*7*8 = 336.

Alternatively,

2*2*2-2=6
3*3*3-3=24
4*4*4-4=60
5*5*5-5=120
6*6*6-6=210
7*7*7-7=336.

Complete the series 6, 11, 31, 121, 601, ?

6788

correct answer c

First Term = 6.

Second term = 6*2 -1 = 11.

Third term = 11* 3 - 2 = 31.

Fourth term = 31 *4 - 3 = 124 -3 = 121.

Fifth term = 121*5 - 4 = 601.

Sixth term = 601 *6 = 3606 - 5 = 3601.

Complete the series 7, 11, 19, 35, 67, ?

131

134

445

correct answer b

Last Term *2 - 3 = Next Term.

First Term = 7.

Second Term = 7 *2 -3 = 11.

Third Term = 11 *2 - 3 = 19.

Fourth Term = 19 *2 - 3 = 35.

Fifth Term = 35 *2 - 3 = 67.

Sixth Term = 67 *2 -3 = 131.

Complete the series 8, 22, 64, 190, 568, ?

1702

6445

correct answer a

Logic:
Previous Term *3 - 2 = Next term.

First Term = 8.

Second term = 8 *3 - 2 = 24 -2 = 22.

Third term = 22 *3 -2 = 64.

Fourth term = 64 *3 -2 = 190.

Fifth Term = 190 *3 - 2 = 568.

Sixth Term = 568 *3 -2 = 1704 -2 = 1702.

Complete the series 5760, 2880, 960, 240, 48, ?

correct answer b

First Term = 5760.

Second term = 5760 /2 = 2880.

Third Term = 2880/3 = 960.

Fourth term = 960/4 = 240.

Fifth term = 240/5 = 48.

So,
Required term = 48/6 = 8.
