It's the one by the same composer that was published immediately following the publication of his Symphony #49. Very few composers ever wrote that many symphonies.
What is the mode of numbers 10,39,71,76,37,25,36
The average is 85.8
39
It is exactly the same as in the question.
78 - (-49) is the same as 78 + 49 which equals 127
Indium, (In) atom number 49, has:49 protons (same as atom number)49 electrons (same as protons in the UNcharged neutral atom)113-49=64 neutrons in In-113 isotope or 115-49=66 neutrons in In-115 isotope,both are natural occurring isotopes of In (5% and 95% respectively).

The answer is 7. Because 7X7=49 then 49-7= 42!
Assuming the sequence does not merely skip from 13 to 49, and instead carries on in the same pattern, the sequence proceeds thus:1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49.This is thirteen terms. The formula for finding these terms is 4x-3.
