Find An For Each Of The Following Arithmetic Sequence, 1.A1=5 , D=4 , N=11, 2.A1=14 , D= -3 , N=25, 3.A1 =12 , D= 1/2 , N=16, 4.-10 , -6 , -2 , 2 ,6 N

Find an for each of the following arithmetic sequence

1.a1=5 , d=4 , n=11
2.a1=14 , d= -3 , n=25
3.a1 =12 , d= 1/2 , n=16
4.-10 , -6 , -2 , 2 ,6 n=27

Step-by-step explanation:

${a}^{n} = {a}^{1} + (n - 1)d$

${a}^{11} = 5 + (11 - 1)4$

${a}^{11} = 5 + (10)(4)$

${a}^{11} = 45$

${a}^{25} = 14 + (25 - 4) - 3$

${a}^{25} = 14 + (24)(3)$

${a}^{25} = 14 + 72$

${a}^{25} = 86$
