Question.  5

The next number in the pattern –62, –37, –12, –– is

(a)

25

(b)

13

(c)

0

(d)

–13

Detailed Answer with Explanation:

Look at how the numbers change from one term to the next.

From −62 to −37:

(-62 + 25 = -37)

From −37 to −12:

(-37 + 25 = -12)

So the rule is: add 25 each time.

Next term after −12:

(-12 + 25 = 13)

Therefore, the next number is 13.
