An arithmetic progression has first term 11 and Fourth term 32. Fine the sum of the first nine term
schepotkina [342]

Let the first term be a, 4th term be a_{4}, difference between terms be d, and sum of first nine terms be S_{9}.

a_{4} = a + 3d

32 = 11 + 3d

3d = 32 - 11

3d = 21

d = 7

S_{9} = \frac{9}{2} (2a + (9-1)d)

   = \frac{9}{2} (22+56)

   = 9(11+28)

   = 9(39)

   = 325

Sum of first nine terms is 351.
