Question

Consider the arithmetic sequence 12, 23, 34........ What is the 10th term of this sequence? Is 1111 a term of this sequence? Why? Write the 'n' term?

Answer 1

Answer:

Step-by-step explanation:

THE A.P is: 12,23,34,45......

the first term(a)=12

the commomn difference(d)=11

the general term $a_{n}$=a+(n-1)d=12+(n-1)11

therefore the 10th term $a_{10$=12+(10-1)11=111

checking if 1111 is a term

1111=12+(n-1)11

n-1=1099/11=99.909

n=1+99.909

n=100.909

as n is not a natural number 1111 is not a term of the sequence
