Letter Series — Type I
The questions here are similar to the
questions in Number Series Type I. Instead of numbers we have letters of the
alphabet given here. We have to first identify the pattern that the series of
letters follow. Then, %c have to find the missing letter based on the pattern
already identified In Number Series, we sass different patterns that the
numbers in the series can follow like squares, cubes. In letter series,
obviously, patterns like squares, cubes will not be possible. In I ester
Series, in general, we have a series with constant or increasing or decreasing
differences. The position of the letters in the English alphabet is considered
to he the value of the alphabet in questions on L otter Series. Also, when we
are counting, after we count from A to Z, we again start with A, i.e., we treat
the letters as being cyclic in nature. Like in Number Series, in this type of I
ester Series also, we can have a -combination- of series, 0 series are combined
and given. We need to identify the pattern in the two series to find out the
missing letter, Sometimes, there will he some special types of series also.
Look at a few examples to understand questions on Letter Series. .
Worked out examples:
Example 1.
Find the next Latter in the series
D,
G.J, M, P, ------ .
(a)
Q
(b)
R
(c)
S
(d)
T
Solution.
Three
letters are added to each letter to get the next letter in the series.
Example 2.
Find
the next letter in the series. .
A,
B, D, FI,
(a)
L
(b)
N
(c)
R
(d)
P
Solution.
Each
letter in the given series is multiplied with 2 to get the next letter in the
series. .
A
x 1
&⇒1 x = 2 and the
2" letter is B, B x 2
&⇒2
x 2 -- 4 and the 4th' letter is D. Similarly, H x 2 . 8 x 2 = 16 and
the 16' letter is P .
Example 3.
What
is the next letter in the series?
B,
D, G, K, P……………..
(a)
S
(b)
V
(c)
W
(d)
X
Solution.
6
= 16 + 6 = 22 and the 22' letter is V. Choice (b).
Example 4.
I,
X, J, W, K, V, L,
(a)
M
(b)
U
(c)
S
(d)
T
Solution.
The
given series is an alternate series. I+1, J+1', K+1,
L is one series and X-1, V-1, is the other series. X —
I = W, W — 1 = V and V — 1 = 22 — 1 = 21 and the 21th letter is U.
Choice
(b)
