Q. h(n)=−91⋅(−71)n−1Complete the recursive formula of h(n).h(1)=□h(n)=h(n−1)⋅□
Calculate h(2): Now, let's find h(2) to see the pattern between consecutive terms.h(2)=−91×(−(1)/7)2−1=−91×(−(1)/7)1=−91×(−1/7)=91/7=13
Verify pattern with h(3): We can see that h(2) is obtained by multiplying h(1) by −71. Let's verify this pattern by calculating h(3) and checking if it follows the same rule. h(\(3) = −91 \times \left(-\frac{1}{7}\right)^{3−1} = −91 \times \left(-\frac{1}{7}\right)^2 = −91 \times \frac{1}{49} = -\frac{91}{49} = −91 \times \left(\frac{1}{7}\right)^2 = -\frac{91}{7} \times \frac{1}{7} = 13 \times \left(-\frac{1}{7}\right) = -\frac{13}{7} = −1.85714285714 \text{ (approximately)}
Establish recursive formula: The pattern is consistent. Each term h(n) is obtained by multiplying the previous term h(n−1) by −71.Therefore, the recursive formula for h(n) is:h(n)=h(n−1)×(−71)
Write complete formula: Now we can write the complete recursive formula for the sequence:h(1)=−91h(n)=h(n−1)×(−71) for n > 1
