Answer:
Jane had 45 customers in her first 5 days.
Step-by-step explanation:
To find how many customers Jane had in her first five days, we must calculate how many she had each day and add them up. Let's find the first five values of this sequence.
a₁ = 2*1 + 3 = 5
a₂ = 2*2 + 3 = 7
a₃ = 2*3 + 3 = 9
a₄ = 2*4 + 3 = 11
a₅ = 2*5 + 3 = 13
5 + 7 + 9 + 11 + 13 = 45, so Jane had 45 customers in her first 5 days.
