Write the first five of the sequence defined by the recurive formal t1=3 and tn=tn-1+5

3, 8, 13, 18, 23

Step-by-step explanation:

To find the first 5 terms substitute n = 2, 3, 4, 5 into the recursive formula, that is

t₂ = t₁ + 5 = 3 + 5 = 8

t₃ = t₂ + 5 = 8 + 5 = 13

t₄ = t₃ + 5 = 13 + 5 = 18

t₅ = t₄ + 5 = 18 + 5 = 23

The first 5 terms are 3, 8, 13, 18, 23
