What will be the next term of the arithmetic progression (12,17,22,27,\ldots)?

Answer and explanation

Correct answer: (32)

The direct answer is option D, 32. Compare consecutive terms: \(17-12=5\), \(22-17=5\), and \(27-22=5\). Thus the common difference is 5. Add it to the last shown term: \(27+5=32\). Option D is correct. Option A, 29, would increase by only 2; option B, 30, would increase by 3; and option C, 31, would increase by 4. None preserves the common difference of 5. This is an arithmetic progression, so the general rule would be \(a_n=12+(n-1)5\), which also predicts the next term when \(n=5\): \(12+4(5)=32\). The safest method is to calculate the differences rather than assume the numbers are being rounded or changed irregularly. Memory cue: in a constant-step sequence, the next term is the last term plus the repeated step.
