Question

find the missing alphabet : Z,X,S,I,R,R,?

Answer 1

It is I as:
Z - 2 = X
X - 5 = S
S - 10 = I
I - 17 = R
R - 26 = R
R - 37 = G
G - 50 = I
The series 2, 5, 10, 17, 26, 37, 50 is obtained by the pattern +3, +5, +7, +9, . . . .They are the odd numbers...
Hope this helps :)

Answer 2

Answer:

Letter I.

Step-by-step explanation:

Given,

Sequence: Z, X, S, I, R, R

We see that,

2 alphabets before Z = X

5 alphabets before X = S

10 alphabets before S = I

17 alphabets before I = R

26 alphabets before R = R

37 alphabets before R = G

50 alphabets before G = I

The series 2, 5, 10, 17, 26, 37, 50 is obtained by the pattern +3, +5, +7, +9

Hence, the letter is I.
