Question

find 30m term of 10, 7, 4...​

Answer 1

Solution

Given sequence is 10 , 7 , 4

First Term(a) = 10

Common difference (d) is a₂ - a₁ = 7 - 10 = -3

Number of term (n) is 30

Formula

Tₙ = a + ( n - 1 )d

By putting the value on formula we get

⇒T₃₀ = 10 + ( 30 - 1)(-3)

⇒T₃₀ = 10 - 29 × 3

⇒T₃₀ = 10 - 87

⇒T₃₀ = -77

Answer is -77
