Question

Write the algebraic expression for Sequence of odd numbers

Answer 1

sequence = 1 , 3 , 5 , 7 , 9,...

Algebraic form formula = dn + f - d

= 2n + 1 - 2

= 2n + -1

Answer 2

• xn = 2xn-1 =2n-1 So algebraic form of odd sequences = 2n-1 ii) Sequence of natural numbers which leave remainder 1 when division by 3 are 1, 4, 7, 10, . and position 1,2,3,4, .iii) Sequence of natural numbers ending in 1 are 1, 11, 21, 31, .
