$71$ $72$ $73$ $74$ $75$ $76$ $77$ $78$ $79$ $80$

$81$ $82$ $83$ $84$ $85$ $86$ $87$ $88$ $89$ $90$

$91$ $92$ $93$ $94$ $95$ $96$ $97$ $98$ $99$ $\times$

Let us circle every second number starting from $1$ means circle the number by skip counting $2' s$ .

We know that,

Skip counting by twos means add $2$ to the first circled number to get the next circled number.

That is, $73$

Now,

$1$ $2$ $3$ $83$ $84$ $6$ $7$ $8$ $9$ $10$

$11$ $12$ $13$ $94$ $95$ $16$ $17$ $18$ $19$ $20$

$21$ $22$ $23$ $24$ $25$ $26$ $27$ $28$ $29$ $30$

$31$ $32$ $33$ $34$ $35$ $36$ $37$ $38$ $39$ $40$

$41$ $42$ $43$ $44$ $45$ $46$ $47$ $48$ $49$ $50$

$51$ $52$ $53$ $54$ $55$ $56$ $57$ $58$ $59$ $60$

$61$ $62$ $63$ $64$ $65$ $66$ $67$ $68$ $69$ $70$

$71$ $72$ $73$ $74$ $75$ $76$ $77$ $78$ $79$ $80$

$81$ $82$ $83$ $84$ $85$ $86$ $87$ $88$ $89$ $90$

$91$ $92$ $93$ $94$ $95$ $96$ $97$ $98$ $99$ $\times$

Hence, the every second numbers are circled starting from $1$ .
