Question

Write the 150th term of 2 4 6 8 10​

Answer 1

Given Sequence is

⇒2,4,6,8,10,,,,

⇒First term (a) = 2

⇒Common difference (d) = a₂-a₁ = 4 -2 = 2

To find

⇒Number of term 150

Formula

⇒Tₙ = a+(n-1)d

Now put the value

⇒T₁₅₀ = 2 + (150-1)×2

⇒T₁₅₀ = 2 + 149×2

⇒T₁₅₀ = 2+298

⇒T₁₅₀ = 300

Answer

⇒T₁₅₀ = 300

                                                                                                   

More Information

⇒Nth term = a+(n-1)d

⇒Sum = n/2{2a+(n-1)d}

               or

⇒Sum = n/2(a+l)

where l = a + (n-1)d
