Sudha  (11 years ago)

the question is wrong ,,one more number should b der ie, 73.09
first 3 numbers arranged as: each successive num is sum of prev num+its lowest significant digit... =(41.45+0.05=41.5...,, 41.5+0.5=42),,
next series is subraction =(18.23-0.03=18.2...,, 18.2-0.2=18)
next series is addition+ (73.09+0.09=73.18)
so ans is 73.18

The correct series is 41.45,41.5,42,18.23,18.2,18,73.09

for the first three numbers, each successive number is the sum of the previous number plus the addition of its lowest significant digit

(41.45 + 0.05 = 41.5) (41.5 + 0.5 = 42)

For the next three numbers, the successive number is the previous number minus the previous lowest significant digit

(18.23 - 0.03 = 18.2) (18.2 - 0.2 = 18)

So if the pattern is alternating between those two patterns, the next number would be (73.09 + 0.09 = 73.18)

amswer is 20
simply by converting the significant digits
say 41.45-> 41.5-> 42
18.23->18.2->18->20

senapathi sudhasri  (10 years ago)

ans is 73.1, when we cosider first 3 numbers as sequence then difference is 0.05 and 0.5 similarly 0.03 and 0.2 for next number 73.09 add 0.01 since from sequence first number has 2 digits after decimal and second number has 1 digit after decimal third number has no digits ,this follows for next 18.23,18.2,18 . so to get 1 digit after decimal add 0.01
