Question

find whether 55 is the term of the AP 7,10,13 ​

Answer 1

Answer:

yes

Step-by-step explanation:

given, the AP is 7 , 10, 13

from the above first term=a=7

common difference=(d)=a2-a1=10-7=3

given , the nth term is 55

we know that an=a+(n-1)d

                      55=7+(n-1)3

                      48=(n-1)3

                       16=n-1

                        n=16+1

                        n=17

∴55 is the term of the given AP
