ক্রমিক পাঁচটি জোড় সংখ্যার যোগফল = 2720
অর্থাৎ, \(x +(x+2)+(x+4)+(x+6)+(x+8)=2720\)
গণনা:
\(x +(x+2)+(x+4)+(x+6)+(x+8)=2720\\5x+20=2720\\5x=2700\\x=540\)
এইভাবে, তৃতীয় সংখ্যা \(= x + 4 = 544\)
পঞ্চম সংখ্যা \(= x + 8 = 548\)
তৃতীয় এবং পঞ্চম সংখ্যার যোগফল \( = 544 + 548 = 1092\)
অতএব, তৃতীয় এবং পঞ্চম সংখ্যার যোগফল হল 1092
