Question

CUET PG 2023 — Reasoning PYQ

CUET PG | Reasoning | 2023

Find the missing term in the given number series.

-1,0, 7, 26, 63, ?, 215, 342.......

Choose the correct answer:

Explanation

1. Pattern ki Pehchan

Series ke har term ko niche diye gaye formula se nikala ja sakta hai:

\text{Term} = n^3 - 1

Yahan $n$ ki shuruat $0$ se ho rahi hai ( $n = 0, 1, 2, 3, \dots$ ).

2. Har Term ki Calculation

Pehli term ( $n=0$ ): $0^3 - 1 = 0 - 1 = -1$
Doosri term ( $n=1$ ): $1^3 - 1 = 1 - 1 = 0$
Teesri term ( $n=2$ ): $2^3 - 1 = 8 - 1 = 7$
Chauthi term ( $n=3$ ): $3^3 - 1 = 27 - 1 = 26$
Paanchvi term ( $n=4$ ): $4^3 - 1 = 64 - 1 = 63$

3. Missing Term ki Calculation

Missing term series ki chhathi (6th) term hai, isliye hum $n = 5$ rakhenge:

\text{Missing Term} = 5^3 - 1

\text{Missing Term} = 125 - 1

\text{Missing Term} = 124

4. Agli Terms ki Verification

Saatvi term ( $n=6$ ): $6^3 - 1 = 216 - 1 = 215$
Aathvi term ( $n=7$ ): $7^3 - 1 = 343 - 1 = 342$

Final Answer:

Missing term 124 hai.
