Question

If a1,a2,a3,.....,a10 be in A.P and h1,h2,h3,.....,h10 be in H.P. If a1=h1=2 and a10=h10=3, then the value of a4h7 is ....................

Solution

The common difference of the A.P. is d=a10a19=19
Thus, a4=a1+3d=73
Similarly for the H.P., h1=2 and h10=3
So, 1h1,1h2,.. being in A.P., we have the common difference to be 1h101h19=154
Implying that 1h7=126154=718
h7=187
a4h7=73×187=6
