Question

A sequence can be generated by using the equation shown, where a= 12 and n is a whole number greater than 1an = 1.5+ (n-1)

What are the first four terms in the sequence?

Answer 1

To find the first four terms in the sequence, we can substitute the values of n starting from 2 into the equation and calculate the corresponding terms.

For n = 2:
an = 1.5 + (2-1)
an = 2.5

For n = 3:
an = 1.5 + (3-1)
an = 3.5

For n = 4:
an = 1.5 + (4-1)
an = 4.5

Therefore, the first four terms in the sequence are 2.5, 3.5, 4.5.
