Here are the some more types of number series pattern detailed solutions for SBI Clerk Pre 2019.
3. Geometric Series based series for IBPS Clerk Pre and SBI Clerk 2019:
It is based on either descending or ascending order of numbers and each successive number is obtained by dividing or multiplying the previous number by a specific number.
Ex: 4, 36, 324, 2916 ?
Sol: 4 x 9 = 36, 36 x 9 = 324, 324 x 9 = 2916, 2916 x 9 = 26244.
4. Arithmetic Series for SBI Clerk Pre 2019 and IBPS Clerk Pre 2019 with Explanation:
It consists of a series in which the next term is obtained by adding/subtracting a constant number to its previous term. Example: 4, 9, 14, 19, 24, 29, 34 in which the number to be added to get the new number is 5. Now, we get an arithmetic sequence 2,3,4,5.
Two-stage Type Series:
In a two step Arithmetic series, the differences of consecutive numbers themselves form an arithmetic series.
Ex: 1, 3, 6, 10, 15.....
Sol: 3 - 1 = 2, 6 - 3 = 3, 10 - 6 = 4, 15 - 10 = 5....
Now, we get an arithmetic sequence 2, 3, 4, 5
5. Mixed Series for SBI Clerk 2019 with Explanation:
This particular type of series may have more than one pattern arranged in a single series or it may have been created according to any of the unorthodox rules.
Ex: 10, 22, 46, 94, 190,?
Sol:
10 x 2 = 20 +2 = 22,
22 x 2 = 44 + 2 = 46,
46 x 2 = 92 + 2 = 94,
94 x 2 = 188 + 2 = 190,
190 x 2 = 380 + 2 = 382.
So the missing number is 382.
6. Arithmetic –Geometric Series for SBI Clerk 2019:
As the name suggests, Arithmetic –Geometric series is formed by a peculiar combination of Arithmetic and Geometric series. An important property of Arithmetic- Geometric series is that the differences of consecutive terms are in Geometric Sequence they have seen in LIC AAO, LIC AAO, IBPS Clerk, SBI Clerk, NIACL and LIC Exams.
Ex: 1, 4, 8, 11, 22, 25, ?
Sol : Series Type +3 , X2 ( i.e Arithmetic and Geometric Mixing)
1 + 3 = 4, 4 X 2 = 8, 8 + 3 = 11, 11 X 2 = 22, 22 + 3 = 25, 25 X 2 = 50
Geometric - Arithmetic Series is the reverse of Arithmetic - Geometric Series. The differences of suggestive terms are in Arithmetic Series is being asked LIC AAO and
SBI Clerk 2019 Exam.
Ex: 1, 2, 6, 36, 44, 440, ?
Sol: Series Type - × 2, + 4, × 6, +8 , × 10
1 × 2 = 2, 2 + 4 = 6, 6 × 6 = 36, 36 + 8 = 44, 44 × 10 = 440, 440 + 12 = 452
7. Twin/Alternate Number Series for SBI Clerk 2019:
As the name of the series specifies, this type of series may consist of two series combined into a single series. The alternating terms of this series may form an independent series in itself.
Ex: 3, 4, 8, 10, 13, 16 ? ?
Sol: As we can see, there are two series formed
Series 1: 3, 8, 13 with a common difference of 5
Series 2: 4, 10, 16 with a common difference of 6
So, next two terms of the series should be 18 & 22 respectively.
