Question

The nth term of a sequence is 45 - 4n
Work out the first three terms.

Answer 1

Answer: 41, 37, 33

Explanation:

first term is when n = 1

45- (4 x 1)= 41

second term is when n = 2

45- (4 x2) = 37

third term is when n = 3

45- (4 x3) =33

Answer 2

`41,37 ,33`

Explanation:

`\text{Nth term} = 45-4n\\\\\text{1st term} = 45 - 4 \cdot 1 = 45 - 4 = 41\\\\\text{2nd term} = 45- 4 \cdot 2 = 45 -8 = 37\\\\\text{3rd term} = 45 -4\cdot 2 = 45 - 12 = 33\\\\\text{Hence, the first three terms are:}~ 41,37 ,33`
