Question

if for ap d=8 wht us value if t5 -t2​

Answer 1

Answer:

24

Step-by-step explanation:

$\sf d = 8 \\ \sf {T}_{5} - {T}_{2} = ? \\ \\ \sf We\:know\:that \\ \\ \sf {T}_{n} = a + (n-1)d \\ \\ \sf {T}_{5} = a + ( 5 - 1 )d = a + 4d \\ \\ \sf {T}_{2} = a + ( 2 - 1 )d = a + d \\ \\ \sf {T}_{5} - {T}_{2} = a + 4d - a - d \\ \\ \sf = 3d \\ \\ \sf = 3 × 8 = 24$

Step-by-step explanation:

\begin{gathered}\sf d = 8 \\ \sf {T}_{5} - {T}_{2} = ? \\ \\ \sf We\:know\:that \\ \\ \sf {T}_{n} = a + (n-1)d \\ \\ \sf {T}_{5} = a + ( 5 - 1 )d = a + 4d \\ \\ \sf {T}_{2} = a + ( 2 - 1 )d = a + d \\ \\ \sf {T}_{5} - {T}_{2} = a + 4d - a - d \\ \\ \sf = 3d \\ \\ \sf = 3 × 8 = 24\end{gathered}
