Number Series

The series follows an alternating pattern: +16, -20, +24, -28, +32, -36. 112+16=128, 128-20=108, 108+24=132, 132-28=104, 104+32=136 (not 134), 136-36=100. Thus, 134 is the wrong number.

The pattern is: 5*1+1=6, 6*2+2=14, 14*3+3=45, 45*4+4=184, 184*5+5=925. The number 920 is incorrect; it should be 925.

Differences: 22-10=12, 35-22=13, 50-35=15, 68-50=18, 92-68=24, 117-92=25. The differences are 12, 13, 15, 18, 22, 25. The pattern of differences is +1, +2, +3, +4, +5. 12+1=13, 13+2=15, 15+3=18, 18+4=22. So 92 should be 68+22=90. Then 117-90=27, which fits the +5 pattern.

Pattern: 64*0.5+2=34, 34*1+2=36, 36*1.5+2=56, 56*2+2=114, 114*2.5+2=287, 287*3+2=863. The term 860 is incorrect.

The pattern is: 2*2+1=5, 5*3+2=17, 17*4+3=71, 71*5+4=359, 359*6+5=2159.

Differences: 22-18=4, 25-22=3, 30-25=5, 36-30=6. The pattern of differences should be consistent. If the series was 18, 21, 25, 30, 36 (diffs 3, 4, 5, 6), then 22 is the wrong term.

The pattern is to multiply by 4 and add 4: 1 becomes 8, 8 becomes 36, and 36 becomes 148. The next term should be 148 x 4 + 4 = 596, so 586 is wrong.

The pattern is: 480 * 2 + 1 = 961; 961 * 3 + 4 = 2887; 2887 * 5 + 9 = 14444; 14444 * 7 + 16 = 101124. The term 101112 is incorrect because the sequence follows adding the square of consecutive odd numbers (1^2, 2^2, 3^2, 4^2).

Differences: 1246-1234=12, 1264-1246=18, 1287-1264=23, 1318-1287=31, 1354-1318=36. The pattern of differences is 12, 18, 24, 30, 36. 1287 is incorrect; it should be 1264 + 24 = 1288.
