First four terms of the given Arithmetic Sequence

#color(brown)(= 17.3, 18.2, 19.1, 20#

It’s an Arithmetic Sequence with first term #a = 17.3# and common difference #d = 0.9#

To find #a_2, a_3, a_4# terms

Formula for #n^(th)# term #a_n = a + (n-1)d#

Applying the above formula,

#a_2 = a + (2-1) * d = 17.3 + 0.9 = = 18.2#

#a_3 = a + (3-1) * d = 17.3 + 2*0.9 = = 19.1#

#a_4 = a + (4-1) * d = 17.3 + 3*0.9 = = 20#
