WitrynaSince this holds for all n, we can plug in n=-1 and n=1 to get two equations: 1/-3=A/-1 +B/3. 1/5=A/1+B/5. Clean up the fractions to get -1=-3A+B and 1=5A+B. Subtract the second equation from the first to get -2=-8A, or A=1/4. So B=-1/4. So now, we're seeking the sum from n=1 to ∞ of (1/ (4n)-1/4 (n+4)). WitrynaPlay this game to review Mathematics.

Witrynan t h term of an A.P. is a n = a 1 + n-1 d where a 1 = first term, d = common difference. Given, a 1 = 1, a n = 300. a n = a 1 + n-1 d 300 = 1 + n-1 d 299 = n-1 d n-1 = 299 d. Now, given that common difference is integer and also n-1 will be an integer. So, d = 23 or 13. If d = 23, ⇒ n-1 = 13 ⇒ n = 14.
