Answer:
a = 2
Step-by-step explanation:
In an AP the difference between consecutive terms is common (equal), thus
t₂ - t₁ = t₃ - t₂ , that is
2a + 1 - (a + 1) = 4a - 1 - (2a + 1) ← distribute and simplify both sides
2a + 1 - a - 1 = 4a - 1 - 2a - 1
a = 2a - 2 ( subtract 2a from both sides )
- a = - 2 ( multiply both sides by - 1 )
a = 2

Answer:
2 2/5
Step-by-step explanation:
Given 4/5÷1/3
Multiply 4/5 with the reciprocal of 1/3 as shown;
= 4/5 × 1/(1/3)
= 4/5 × 3/1
= 12/5
= 2 2/5
The quotient is 2 2/5
