What should come next in the following series? A4, C16, F36, J64, ?
O100
Each term has a letter part and a number part; analyse the two patterns separately.
Letters: A, C, F, J, ? Their positions are 1, 3, 6, 10, and the gaps increase as +2, +3, +4, so the next gap is +5 giving position \(10 + 5 = 15\), which is O.
Numbers: 4, 16, 36, 64, ? These are squares of even numbers: \(2^2 = 4\), \(4^2 = 16\), \(6^2 = 36\), \(8^2 = 64\).
The next even number is 10, so the next value is \(10^2 = 100\).
Combining the letter O with the number 100 gives the next term.
Options N100, K100 and L100 have the wrong letter for position 15.
Hence the next term is O100.
