Answer 1

Answer:

1+4 = 5 : 2+5 = 12 ; 3+6 = 21 ; 8+11 = ?

If we see the series then we will find the numbers in the series in this way.

# (1*4) + 1 = 5

4+1 = 5

# (2*5) +2 = 12

10 + 2 = 12

# (3*6) + 3 = 21

18 + 3 = 21

# (4*7) + 4 = 32 [Which is not given in the series]

28 + 4 = 32

# (5*8) + 5 = 45 [Which is not given in the series]

40 + 5 = 45

# (6*9) + 6 = 60 [Which is not given in the series]

54 + 6 = 60

# (7*10) + 7 = 77 [Which is also not given in the series]

70 + 7 = 77

# (8*11) + 8 = 96 [Number about which is the question is asked]

88 + 8 = 96

So, the missing number in the series will be 96.
