1.	& MR2. समांन्तर श्रेणी : 2, 6, 10, 14.,... का कौन सा पद 82 हैं
Answer» Here, a = 2 d = 6 - 2 = 4 an = 82 an = a + (n - 1)dSubstituting a, d and an,=> 82 = 2 + (n - 1)(4)=> 82 = 2 + 4n - 4=> 82 = 4n - 2=> 4n = 82 + 2=> 4n = 84=> n = 21 Therefore, 82 is the 21st term.

Answer»

Here,

a = 2 d = 6 - 2 = 4 an = 82

an = a + (n - 1)dSubstituting a, d and an,=> 82 = 2 + (n - 1)(4)=> 82 = 2 + 4n - 4=> 82 = 4n - 2=> 4n = 82 + 2=> 4n = 84=> n = 21

Therefore, 82 is the 21st term.
