<p>Table:
Row 1: 24 26 28 30
Row 2: 10 15 20 25</p>

<p>In the top row of the table above, the first term of the sequence is 24, and each term after the first is 2 more than the preceding term. In the bottom row, the first term of the sequence is 10, and each term after the first is 5 more than the preceding term. If these sequences continue indefinitely, in how many columns of the table will the terms from both sequences be equal?
a) None
B) One
C) two
d) three
e) More than three</p>

<p>Please show how you do it too
thanks</p>

2

<p>None. Continue the sequences:</p>

<p>32 34 36 38 40
30 35 40 45 50</p>

<p>The second sequence overtakes the first without ever sharing a common value.</p>

3

<p>I would say none.</p>

<p>Row 1: 24 26 28 30 32 34 36
Row 2: 10 15 20 25 30 35 40</p>

<p>Already row 2 has surpassed row 1, and row 1 will never be able to catch up, so no columns of the table will have equal terms</p>

<p>Edit: dang pioneer, beat me to it :)</p>
