Question

Find the missing term in H4J and F9N, E13P,D18R

Answer 1

given: 4 terms are given: H4J, F9N, E13P, D18R .

to find: one missing term is to be find.

Explanation:

Step 1:

H4J, F9N, E13P, D18R    (given)

if we see at first character of first term then H→G→F→E→D.

we are going backward from H to G then G to F then F to E and then E to D.

from this it is clear that G is missing as first character of the missing term.

Step 2:

   now we see 2nd character of first term then 4+2=6,

                                                                              6+3=9,

                                                                              9+4=13,

                                                                              13+5=18,

It means 6 is missing as 2nd character of the missing term.

step 3:

now we will see 3rd character of the first term then J→L→N→P→R.

we are going forward from J to R by skipping one letter in between.

It means L is missing as 3rd character of missing term.

step 4:

Missing term is G6L.
