Question

If T₄=7 and T₇= 4, then T₁₀ = ......,select a proper option (a), (b), (c) or (d) from given options so that the statement becomes correct.(All the problems refer to A.P.)
(a) 9
(b) 11
(c)-11
(d) 1

Answer 1

9 is there answer option A

Answer 2

Answer:

Step-by-step explanation:

The formula of nth term of AP=a+(n-1)d,where a is first term and d is common difference.

T4=a+3d=7---(1)

T7=a+6d=4---(2)

Subtract 1 from 2,

3d= -3d=-1

So,

a=10

Now,

T10=10+(9*-1)=10-9=1

Hence, option d is the answer, hope you understood
