\n(12+1)*0.5 = 6.5
\n(6.5+1)*1 = 7.5
\n(7.5+1.5)*1.5=12.75
\n(12.75+1)*2 = 27.5
\n(27.5+1)*2.5 = 71.25
\n(71.25+1)*3 = 216.75<\/p>\n
\nHence, 16*1.5 = 24
\n24*1.5 = 36
\n36*1.5 = 54
\n54*1.5=81
\n81*1.5 = 121.5
\nSo, the next number is 121.5*1.5 = 182.25<\/p>\n
\nFor example, 12\/12 = 1
\n18\/12 = 1.5
\n45\/18 = 2.5 (which is 1+1.5)
\n180\/45 = 4 (which is 1.5+2.5)
\n1170\/180 = 6.5 (which is 2.5+4)
\nHence, the next ratio would be 4+6.5=10.5
\nAnd the required number is 1170*10.5 = 12285<\/p>\n
\nFor example,
\n23-22 = 1
\n27-23 = 4
\n36-27 = 9
\n52-36 = 16
\n77-52 = 25
\nHence, the next difference between the numbers will be 36 and the required number is 77+36 = 113<\/p>\n
\n14 = 16*1 – 2*1
\n24 = 14*2 – 2*2
\n66 = 24*3 – 2*3
\n256 = 66*4 – 2*4
\n1270 = 66*5 – 2*5
\nHence, the next term equals 1270*6 – 2*6 = 7608<\/p>\n
\nThe nth term is of the form,
\n$$T_n=(T_{n-1}\\times n)+n$$
\nThe last term does not follow the pattern and is thus the wrong number in the sequence.<\/p>\n
\n2.5*3 + 4 = 11.5
\n3.5*4 + 5 = 19
\n4.5*5 + 6 = 28.5
\n5.5*6 + 7 = 40<\/p>\n
