Question

the number 593 is a term of the ap formed by the term of 5,9,13..., is it true? check it and find the number of this term ​

Answer 1

Answer:

a=5

d=4

an= a+(n-1 )× d

593=5+(n-1)×4

593-5=(n-1) ×4

588=(n-1)×4

588÷4=n-1

147=n-1

n=148

hence , 593 is a term of the ap since n is a whole number

And , 593 is the 148th term
