Question

find the 30th term of the sequence.


1/2,1,3/2

Answer 1

Common Difference = (1-1/2) 1/2
then by using the equation
nth terms= a+c.d(n-1)
= 1/2+ (30-1)1/2
= 1/2 + (29)/2
= 30/2
= 15

Answer 2

FIRST TERM (a) :- 0.5

COMMON DIFFERENCE (d) :- 1 - 0.5 = 0.5

FORMULA FOR FINDING nth TERM :- a + (n - 1)d

= 1 + (30 - 1)0.5

=31/2
