Application +4 | -1

a_{1}, a_{2}, a_{3}, \ldots . a_{n}

are in A.P. and

a_{1}+a_{4}+a_{7}+\ldots+a_{16}=114

, then

a_{1}+a_{6}+a_{11}+a_{16}

is equal to:

View answer and explanation

Correct option: B

Option B (76) is correct because the sum a_1 + a_6 + a_11 + a_16 can be expressed in terms of a_1 + a_16, which is derived from the given equation.
