Answer:
arithematic sequence =7n-5
aₙ=7n-5
general term of arithematic sequence =a+(n-1)d
a+(n-1)d=7n-5
adding and subtracting 7 on RHS,we get
a+(n-1)d=7n-7+7-5
=7(n-1)+2
=2+(n-1)7
by comparing a=2,d=7 (here 'a' is the first term of sequence,
'd' is common difference of AP)
general form of arithmetic sequence is a,a+d,a+2d,.......a+(n-1)d.
therefore arithmetic sequence is 2,9,16,23,30,........
