Each consecutive terms is increased by 8 and so the next term is 49
9, 17, 25, 33, 41
It is increasing by 4 and the nth term is 4n+1
Did you notice this goes up in 8s? 9+8=17 17+8=25 ... 41+8=49 So the missing number is 25+8=33 Then 33+8=41 and so the series continues.
33. ( how i got it 25+41= 66; 66/2= 33)
(25+26+27+28+29+30+31+32+33+34+35+36+37+38+39+40+41) / 17 => 561/17 => 33 The Answer
33
66
The difference between successive terms is 8 tn = 8n + 9 or 8(n+1)+1 where n = 1,2,3,...
17 + 11 + (25-12) = 17 + 11 + 25 - 12 = 41.
It is 33.
It is 33.
it is 33; you can add all up and divide by 17, or simply add first and last and divide by 2
