Odd terms => (1 , 45 , 89 , x) --> C.d = 44
even terms => (100 , 143 , 186) --> c.d = 43

=> x = 89 + 44 = 133

100-1=99
45-100=-55
143-45=98
89-143=-54
186-89=97
therefore the next difference =-54+1=-53
therefore the next number=-53+186=133
option 1

Differences of the numbers are
99,-55,98,-54,97
Hence the next difference wil be -53
Hence the next number is 186-53 = 133
Hence option no.1
