Question

if an AP first term is 5 common difference is 2 and n= 24 find solution of first 24 term​

Answer 1

Answer:

672

Step-by-step explanation:

given a=5; d=2; n=24

=> Sₙ = $\frac{n}{2}$ (2a+(n-1)d)

 ∴ S₂₄ = $\frac{24}{2}$( 2(5)+(24-1)2 )

           = 12 (10+23(2) )

           = 12 (10+46)

           = 12(56)

           = 672

Answer 2

Answer:

first term is(a) =5

common difference(d) =2

n=24

s24=n
