Heya,
a1 +a2 +a3 + a4 = 32
a + a +d + a+2d+a+3d =32
4a +6d =32
2a +3d=16 ------------(1)
a1 * a4/a2*a3 = 7/15 ---------(2)
Simplifying the 2nd equation in a similar way to the first, we get the 3rd equation.
Now, solve the 3rd equation for a and d. Wewill get the first term and the difference.
Since they have asked us to find the number, we have to find 'a'.
