Answer 2

Answer:

first term=a=2,b=3

=(a+b)=2+3=5

=(a+b)=2+3=5 first term =5

common different =2×2=4

common different =2×2=4algebra form = dn+(f-d)

common different =2×2=4algebra form = dn+(f-d) =4n+(5-4)

common different =2×2=4algebra form = dn+(f-d) =4n+(5-4) =4n+1

common different =2×2=4algebra form = dn+(f-d) =4n+(5-4) =4n+1sum of first 10 term = X1 +9d

common different =2×2=4algebra form = dn+(f-d) =4n+(5-4) =4n+1sum of first 10 term = X1 +9d 5+9×4=5+36=41

common different =2×2=4algebra form = dn+(f-d) =4n+(5-4) =4n+1sum of first 10 term = X1 +9d 5+9×4=5+36=41 Step-by-step explanation:

1. common different =2×2=4algebra form = dn+(f-d) =4n+(5-4) =4n+1sum of first 10 term = X1 +9d 5+9×4=5+36=41 Step-by-step explanation:Hope mark sariydi
