Answer: The sum of given term is 185

Step-by-step explanation:

here, First term (f) = 5 , n= 10 ,common difference (d) =3

10th term = f + (n - 1) d

= 5 + (10 -1) 3

= 5+ 9*3

=5+27

Hence, 10th term=32

sum of 10 terms = n/2 ( f+ 10th term )

=10/2 ( 5+32)

= 5 ( 37 )

=185

therefore, sum of the given terms is 185
