Another number series whose first term is 23 follows the same logic as followed in series ii L and K...........

Quantitative Aptitude(IBPS PO) Number series

Given below there are three number series (I, II, and III). One of the numbers in each series (I, II, and III) is wrong or (odd one out).

Series I: 590, 615, 651, 711, 795, 927

Series II: 64, 164, 285, 510, 546, 770

Series III: 18, 25.5, 40.5, 63, 93, 131

Another number series, whose first term is 23, follows the same logic as followed in series (ii). L and K are the fifth and third terms of the new series respectively, then what is the value of (L - K)?

Explanation:

Correct option 3: 288

Series I: 590, 615, 651, 711, 795, 927
Logic used:
591+ (12 x 2) = 615
615+ (12 x 3) = 651
651+ (12 x 5) = 711
711+ (12 x 7) = 795
795+ (12x11)=927
The wrong number in the series is (590).
Serles II: 64, 164, 285, 510, 546, 770
Logic used:
64+ (6+4)²=164
164+ (1 +6+4)² = 285
285+ (2+8+5)²=510
510+ (5+1+0)² = 546
546+ (5+4+6)²= 771
The wrong number in the series is (770).
Series III:18, 25.5, 40.5, 63, 93, 131
18+ 7.5 = 25.5
25.5+ 15 = 40.5
40.5 + 22.5 = 63
63+30=93
93 + 37.5 = 130.5
The wrong number in the series is (131).
First term of the series is 23, so the number series will be:
23
23+ (2+3)² = 48
48+ (4+8)²=192 K
192+(1+9+2)² = 336
336+(3+3+6)²= 480 = L
So, the value of (L-K) is (480-192) = 288
