Answer 1

Answer:

-0.30952380952$Second term - First term =−2−(3)=−5Third term - Second term =−7−(−2)=−5So, the given sequence is an A.P. with a common difference of −5.Since each term of an A.P. is obtained by adding common difference to the preceding term.∴a 5​ =a 4​ +(−5)=−12+(−5)=−17a 6​ =a 5​ +(−5)=−17+(−5)=−22and, a 7​ =a 6​ +(−5)=−22+(−5)=−27$
