The next number is 26-2 = 24 followed by 24-1 = 23
Ans: 25 26 Reasoning: read every second number. From first number: 30 29 28 27 26 __(pattern of -1). From second number: 21 22 23 24 25 __(pattern of +1)
Oh honey, it's like a rollercoaster ride with these numbers. The pattern here is going up by 3, then down by 4, then up by 3 again, and so on. So, following that trend, the next number would be 25. But hey, who am I to tell you what to do? Do whatever floats your boat!
26. The sequence can be seen either as decreasing multiples of 13 or, more generally, 65 - 13n where n = 1, 2, 3, ...
Expressed in words, the equivalent ordinal number for the cardinal number 26 would be twenty-sixth.
each pair is a double i.e. 14 and 28, 18 and 36, 26 and 52 and so on. Each successive pair is increased by double the last increase. So looking at every other number, 14+4=18 18+8=26 26+16=42 so the next pair would be 42+32=74 and its double 148 Another way to think of it is the first number in successive pair increases by 4 then 8 then 16 then 32. The second number in a pair increases by 8 then 16 then 32.
Personally, the most logical for me would be 22.
assuming it keeps the same pattern of +10 -5 alternating then the next number would be 26

It is: 26+7 = 33
The proton number for an isotope of iron with 59 mass number would be 26, as iron has 26 protons in its nucleus. Since the mass number is 59 and the proton number is 26, the number of neutrons would be 33 (59 - 26).

The number of Neutrons and Protons in the nucleus.So it would be 26 Protons and 30 Neutrons so...26+30=56<so that is the mass number.
The mass number of an iron is determined by the total number of protons and neutrons. Iron has an atomic number of 26, meaning it has 26 protons. If the iron atom has 29 neutrons, the mass number would be 26 (protons) + 29 (neutrons) = 55.
The number of atoms would be 292 X Avogadro's Number X number of atoms per molecule of the substance whose moles are in question. The latter value must be specified before a complete answer can be given.
