Question

# You are given two series in two rows. In the first row, a full series is given which follows a specific pattern. The second row has a series, similar to the first series but only first element of this series is produced followed by (A), (B), (C), (D) and (E) for the subsequent elements. You have to complete the series starting with a given number and answer the question that follows. What will come in place of D?a. 91 b. 67 c. 112 d. 187

## Text solutionVerified

Step 1. Identify the given series and the pattern followed by it. The given series in the first row is: 2, 9, 23, 51, 107, 219. The pattern followed by this series is that each term is obtained by multiplying its previous term by 2 and adding 5 to it. Step 2. Identify the given series and the format followed by it. The given series in the second row is: 7, A, B, C, D, E. The format followed by the second series is that the second series starts with the first element of the first series followed by (A), (B), (C), (D), and (E) for the subsequent terms. Step 3. Use the pattern of the first series to complete the second series. Using the pattern of the first series, we can complete the second series as follows: - To find the second element of the second series, we multiply the first element of the second series (which is 7) by 2 and add 5 to it. This gives us: 7 x 2 + 5 = 19. So, the second element of the second series is 19 (A). - To find the third element of the second series, we multiply the second element of the second series (which is 19) by 2 and add 5 to it. This gives us: 19 x 2 + 5 = 43. So, the third element of the second series is 43 (B). - To find the fourth element of the second series, we multiply the third element of the second series (which is 43) by 2 and add 5 to it. This gives us: 43 x 2 + 5 = 91. So, the fourth element of the second series is 91 (C). - To find the fifth element of the second series, we multiply the fourth element of the second series (which is 91) by 2 and add 5 to it. This gives us: 91 x 2 + 5 = 187. So, the fifth element of the second series is 187 (D). Therefore, the answer to the question "What will come in place of D?" is 187.
