In a certain sequence, the term \(a_n\) is defined as the value of x that satisfies the equation \(2 = \frac{x}{2} a_{n 1}\). If \(a_6 =156\), what is the value of \(a_2\)? (A) 1 (B) 6 (C) 16 (D) 26 (E) 106

(A) 1 (B) 6 (C) 16 (D) 26 (E) 106 \(2 = \frac{x}{2} a_{n 1}\) \( \frac{x}{2} =2+a_{n 1}\) \(x=a_n=4+2a_{n1}\), as x is nothing but \(a_n\). Two ways I. Find the lower terms from the given value \(a_n=4+2*a_{n1}\) \(a_6=4+2*a_{5}\) \(156=4+2*a_5……..a_5=76\) \(a_5=4+2*a_{4}\) \(76=4+2*a_4……..a_4=36\) \(a_4=4+2*a_{3}\) \(36=4+2*a_3……..a_3=16\) \(a_3=4+2*a_{2}\) \(16=4+2*a_2……..a_2=6\) II. Use options. A. 1…. \(a_3=4+2*a_{2}=4+2=6……… a_4=4+2*a_{3}=4+12=16……….. a_5=4+2*a_{4}\) \(=4+32=36……….. a_6=4+2*a_{5}=4+72=76\neq 156\) B. 6…. \(a_3=4+2*a_{2}=4+12=16……… a_4=4+2*a_{3}=4+32=36……….. a_5=4+2*a_{4}\) \(=4+72=76……….. a_6=4+2*a_{5}=4+76=156\)…..Correct B
