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
