Find the 5 first terms of the sequence {sn} = {2n-3} and of the sequence {sn} = {4^n} ?

and of the sequence #{sn} = {4^n}#

the n is supposed to be under the s like sub n but idk how to write that... Thank you!

#-1,1,3,5,7" and " 4,16,64,256,1024#

Explanation:

#"to generate the terms in the sequences, substitute"#

#n=1,2,3,4,5" into them"#

#s_n=2n-3#

#s_1=(2xx1-3)=-1#

#s_2=(2xx2)-3=1#

#s_3=(2xx3)-3=3#

#s_4=(2xx4)-3=5#

#s_5=(2xx5)-3=7#

#"similarly for " s_n=4^n#

#s_1=4^1=4#

#s_2=4^2=16#

#s_3=4^3=64#

#s_4=4^4=256#

#s_5=4^5=1024#
