Question

If the 6th term of an ap is minus 10 and its 15 term is minus 46 then find the 10th term of an ap

Answer 1

Hi friend,

Here is your answer,

Let the first term be 'a' and common difference be 'd'
a+5d = -10        ---------------------(1)
a+14d = -46      ---------------------(2)
(2)-(1)
9d  =  -36
  d  =  -4
Put d=4 in (1)
a + 5 * (-4) = -10
a - 20  =  -10
  a  =  10
A₁₀ = a+9d
      = 10 + 9(-4)
      = 10 - 36
      = -26
