\n(7-1) x 2 = 12
\n(12 – 2) x 4 = 40
\n(40 – 3) x 6 = 222
\n(222 – 4) x 8 = 1744 \u2260 1742
\n(1744 – 5) x 10 = 17390
\n(17390 – 6) x 12 = 208608<\/p>\n
\n4 = 1*2+2 ; 15 = 4*3+3 ; 64 = 15*4+4 ; 325 = 64*5+5 ; 1956 = 325*6+6
\nThe nth term is of the form,
\nTn=(Tn\u22121\u00d7n)+nT_n=(T_{n-1}\\times n)+nTn\u200b=(Tn\u22121\u200b\u00d7n)+n
\nThe last term does not follow the pattern and is thus the wrong number in the sequence.<\/p>\n
\n5506 – 92 <\/sup>= 5425
\n5425 – 112<\/sup> = 5304
\n5134 – 132<\/sup> = 5135
\n5135 – 152 <\/sup>= 4910
\n4910 – 172<\/sup> = 4621<\/p>\n
\nHence 5531 is the wrong number.<\/p>\n
\n6 + 1 = 7
\n7 + 2 = 9
\n9 + 4 = 13
\n13 + 13 = 26
\n26 + 11 = 37
\n37 + 22 = 69
\nThe number to be added is increasing everytime except for 37 where 11 is added after 13.<\/p>\n
\n(1 x 1) + 2 = 3
\n(3 x 2) + 4 = 10
\n(10 x 3) + 6 = 36
\n(36 x 4) + 8 = 152
\n(152 x 5) + 10 = 770 \u2260760
\n(770 x 6) + 12 = 4632<\/p>\n
\n02<\/sup> + 4 = 4
\n12 <\/sup>+ 2 = 3
\n32<\/sup> + 0 = 9
\n62<\/sup> – 2 = 34
\n102<\/sup> – 4 = 96
\n152 <\/sup>– 6 = 219
