Question

5. find the 43rd term of the sequence.
19.5 , 19.9 , 20.3 , 20.7

Answer 1

36.3

Explanation:

First, we need ro calculate the nth term.

The term to term rule is +0.4, so we know the ntg term contains 0.4n.

The first term is 19.1 more than 0.4, so the nth term is 0.4n +19.1

To find the 43rd term, substitue n with 43.

43 × 0.4 + 19.1 = 17.2 +19.1 = 36.3
