Question

WHCH OF THE FOLLOWING SEQUENCES IS ARITHMETIC? A.12,-12,-12,-12,... B.32,8,2 1/2,... C.12,25/2,13,27/2,... D.1,2,3,5,8?

Answer 1

Answer:

ONLY OPTION A

Step-by-step explanation:

AP=. -12,-12,-12

WHERE , A = -12

AND , COMMON DIFFERENCE D= 0

SO THE COMMON DIFFERENCE IS CONSTANT, THEN IT IS AN AP

IN SHORT , OPTION B AND C ARE NOT AN AP BECAUSE THE DO NOT HAVE A CONSTANT NUMBER WHICH IS COMMON DIFFERENCE, WHEN THE FIXED NUMBER IS NOT EQUAL IN A SEQUENCE, THEN THEY DO NOT FORM AN AP. IF YOU HAVE ANY DOUBT REGARDING THIS , SOLVE THOSE OPTION B AND C WITH THE METHOD WHICH I PROVED FOR OPTION A AND YOU'LL GET THE ANSWER.

THANK YOU AND HAVE A NICE DAY............
