Alpha Numeric Series Multiple Gaps

Alphanumeric Series with Multiple Gaps: 

Introduction: This type of questions the terms of the given series are a combination of letters and numerals, which continue to move according to a set pattern.

Study the following example with multiple gaps to find a suitable next term in the series.

Example :  Find the next term, in the alpha-numeric series: Z1A, X2D, V6G, T21J, R88M, P445P,?

(a) N2676S     (b) N2676T       (c) T2670N      (d) T2676N

Solution: Clearly, the patterns followed by the letters are as follows:

1st letter : Z large overset{-2}{rightarrow} X large overset{-2}{rightarrow} V large overset{-2}{rightarrow} T large overset{-2}{rightarrow} R large overset{-2}{rightarrow} P large overset{-2}{rightarrow}  N

2nd letter : A large overset{+3}{rightarrow} D large overset{+3}{rightarrow} G large overset{+3}{rightarrow} J large overset{+3}{rightarrow} M large overset{+3}{rightarrow} P large overset{+3}{rightarrow}   S

The series formed by the numerals i.e. 1, 2, 6, 21, 88, 445, ...... follows the patterns large times 1+1, large times 2+2, large times 3+3, large times 4+4, large times 5+5,....

So, numeral in the desired term = large 445times 6+6=2676.   Hence, desired term is N2676S.So, the answer is (a).
