A sequence can be generated by using the equation shown, where a1=12 and n is a whole number greater than 1. an=1,5+a(n-1) What are the first four terms in the sequence
To find the first four terms in the sequence, we can use the given equation:
a1 = 12
a2 = 1.5 + a1
= 1.5 + 12
= 13.5
a3 = 1.5 + a2
= 1.5 + 13.5
= 15
a4 = 1.5 + a3
= 1.5 + 15
= 16.5
Therefore, the first four terms in the sequence are:
12, 13.5, 15, 16.5.
