Answer 1

Answer:

If a , b , c are in G . P . , then 22 of the equals 20 . Let s , = 4 – 5 mc2n ? + 9n + 13 ) , then BV r = 1 1 ( b ) n ( n + 3 ) _ 1 _ _ 1 ( d ) n ? 14 . If a , b , c , d are in H . P . , then value of ca - 2 - d - 2 6 - 2 - c - 2 is equals ( a ) 5 nın + 1 ) ( c ) ( n + 1 ) 21 . ... 0 and 2 ( a + c ) x2 + ( b + c ) x = 0 have a common root , then ( a ) a ? , 62 , c ? are
