Solution
The correct option is B 80
from the given series, check the pattern of difference between two consecutive numbers;
155 — 150 = 5
150 — 140 = 10
140 — 125 = 15
125 — 105 = 20
it is clear that the of two consecutive numbers in increasing in a multiple of 5, so the next difference value will be = 25
then next number in the series = 105 - 25 = 80
Hence, next number in the given series will be 80.
