6,215,7,342,8,?
Find the missing term by solving the whole question by proper method.
plz....

Answer 1

this is an harmonic series

we can divide it in two parts

6,7,8..........odd values i.e 1st third and fifth value are separated. as we can clearly see that there is a difference of exactly 1 between each consecutive numbers

similarly we will separate even value 2nd 4th and 6th and

215,342,x

we have to find x

so we will subtract 215 from 342 and then add that number to 342 to get x

342-215=127

x=342+127=469

the number will be 469
