Question

The nth term is 3n+2

a)Work out the first 3 terms in the sequence
b)Work out the tenth term of the sequence

Answer 1

5, 8, 11 and 32

Explanation:

For the first 3 terms, substitute n = 1, 2, 3 into the n th term formula

a₁ = 3(1) + 2 = 3 + 2 = 5

a₂ = 3(2) + 2 = 6 + 2 = 8

a₃ = 3(3) + 2 = 9 + 2 = 11

Similarly for tenth term, let n = 10

a₁₀ = 3(10) + 2 = 30 + 2 = 32
