Question

plz give me the correct answer with complete explanasion​

Answer 1

Given - S10=150 & S5=126

We Need Term 10 = ?

S10=10/2(2*a+(10-1)d)

" " = 10(2a + 9d)

= 20a + 90d

300 = 20a + 90d -- Equation 1

Now Solving S9

S9=9/2(2*a+(9-1)d)

126=9/2(2a+8d)

126*2=9(2a+8d)

252=18a+72d -- Equation 2

Solving 1&2

We Get..

48=2a+18d
