Answer: First we determine the common difference and add , if the result correspond with the next term then we establish the fact that it is AP and if it doesn’t we try if it isa GP sequence.
d = 2nd term - 1st term
= 5 - (-2)
= 5 + 2
= 7, we now add the value of d to the next term to find out if it matches.
Now 7 + 5 = 12
7 + 12 = 19, therefore, the answer is
A and has a different of 7
