Question

the missing term of the A.P 3 ,× 33, 48, is​

Answer 1

Common difference =a2-a1=a3-a2 =a4-a3

=>a2-a1=a3-a2

=>2 (a2)=a1+a3

=>2 (a2)=3+33

=>2 (a2)=36

=>a2=18

Answer 2

Answer:

X=18

Step-by-step explanation:

3,3+15=18,18+15=33,33+15=48

HENCE,X=18

IF YOU HAVE ANY DOUBT PLEASE ASK ON COMMENT SECTION.

NOW,BY USING FORMULA OF AP WE WILL DO IT :

a+(n-1)d where a is first term,n is number of term and d is common difference.

therefore,3+(2-1)15=3+15=18 ( because a=3,n=2 and common difference(d)=15.)
