$ a_1=3,a_2=10, a_3=17; a_4=24$

Work Step by Step

The general formula to find the nth term of a Geometric sequence is given as: $ a_{n}=a_1r^{n-1}$ In order to calculate the General formula of a Geometric sequence we will multiply the first term $ a_1$ by the product of the common ratio with itself one unit less then a Geometric sequence. In order to calculate the first $4$ terms of the sequence we will have to plug $ n=1,2,3,4$ into the given equation. So, we get $ a_1=3,a_2=10, a_3=17; a_4=24$
