In problems involving sequences and series, there are cases where even-indexed terms are written as a(2k) and odd-indexed terms as a(2k-1). Are you sure you can handle that processing correctly? There are many things to be careful about, especially when calculating sums. 🙂 #OnlineTutor #Physics #Mathematics

The translation of the tweet is as follows: "To begin with, in the previous step, we derived * by substituting ① into ② to get a_(2k+1) = a_(2k-1) + 2k. Therefore, in *, the conditions of ① and ① ∧ ② remain, and by carrying over n = 2k-1 and n = 2k, the * formula holds true for both even and odd cases of n. On the other hand, is it correct to understand that * is a recurrence relation that only holds when n is odd, based on the number of terms represented by 2k+1 and 2k-1 in the * formula?"

The tweet translates to: "Please tell me about recurrence relations with different parity terms. I think that by substituting (2) into (1) to derive \( a_{2k+1} = a_{2k-1} + 2k \), it is transformed into \( a_{2n-1} = a_1 + (a_3 - a_1) + ... + a_{2n-1} - a_{2n-3} \) under the condition \( n \geq 2 \). However, I don't understand how this transformation from \( k \) to \( n \) is done. #TeachMeMath #OneToOneCorrespondence" (Note: The mathematical notation has been preserved in the translation.)

Here's the translation of the tweet: "Y5sh2, J2kk4n0h1 S4a2k5a3 S2t1z5 ... A1t5h1k5n5m1m1 ... ... Huh! Was it a dream? I was surprised; I had a nightmare where I was dragged into some kind of shadow I didn't really understand and experimented on... It seems I fainted from not being selected for Switch2... I need to be careful... I guess I'll keep doing strength training and patiently wait until I get selected... x.com/tonjiru_oyaji/..."
