Find the next element that replace the ? Logically 6, 23, 74, 227, ?
686
The series is 6, 23, 74, 227, ? and we must find the term that logically replaces the question mark.
Examine how each term is generated from the one before it rather than looking only at the differences.
From 6 to 23: multiply by 3 and add 5, i.e. \(6 \times 3 + 5 = 23\).
From 23 to 74: \(23 \times 3 + 5 = 74\), which matches the same rule.
From 74 to 227: \(74 \times 3 + 5 = 227\), again the pattern holds.
So the rule of the series is 'multiply the previous term by 3, then add 5'.
Apply it to the last known term: \(227 \times 3 + 5 = 681 + 5 = 686\).
The missing term is therefore 686, which matches the first option.
Hence the correct answer is 686.

(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. E.g.13 − Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
