Question

The next number in the pattern -62, -37,-12,.............is (1 mark)

Answer 1

Difference between 1st number and 2nd number is

= (-37)-(-62)

= -37+62

= 25

Difference between 2nd number and 3rd number is

= (-12) - (-37)

= -12 + 37

= 25

here we can see the difference between each number is 25,

so, the series is A.P series.

so, the next value will

= (-12)+25

= 13
