Question

Which term of the arithmetic progression -7,-12,-17,-22.....will be -82? Is -100 any term of ap? Give reason for answer

Answer 1

Answer:

16th term

no -100 is not in ap

Step-by-step explanation:

an=a0+(n+1)d

-82=-7+(n-1)(-5)

75=(n-1)*5

n=16

-100=-7+(n-1)(-5)

93/5=n-1

n is not a natural number

hence -100 is not a term in ap
