CUET PG 2021 Mathematics PYQ — Find the value of a 4 for th recurrence relation a n = 2a n-1 + 3… | Mathem Solvex

A.
320
B.
221
C.
141
(Correct Answer)
D.
65

Correct Answer:

141

Explanation

1. $a_1$ ki value nikalne ke liye ( $n=1$ ):

a_1 = 2a_0 + 3

a_1 = 2(6) + 3 = 12 + 3 = 15

2. $a_2$ ki value nikalne ke liye ( $n=2$ ):

a_2 = 2a_1 + 3

a_2 = 2(15) + 3 = 30 + 3 = 33

3. $a_3$ ki value nikalne ke liye ( $n=3$ ):

a_3 = 2a_2 + 3

a_3 = 2(33) + 3 = 66 + 3 = 69

4. $a_4$ ki value nikalne ke liye ( $n=4$ ):

a_4 = 2a_3 + 3

a_4 = 2(69) + 3 = 138 + 3 = 141
