Find missing term:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 1097
Going round the centre clockwise from 2, each outer number is the one before it multiplied by 8 (the centre number), plus 1.
\(2\times8+1=17\)
\(17\times8+1=137\)
\(137\times8+1=1097\), the missing number
